Honestly I don't want to call you out but I think you are going into this with the wrong mentality.Hey, I wanted to drop a couple of my thoughts on Dynamax, and why I ultimately believe it should go soon.
Dynamax and Choice Items
There are two opportunity costs of using a Choice Item in NFE, you’re giving up Eviolite which is a powerful defensive tool and you’re giving up your ability to switch moves. Dynamax allows Choiced Pokemon to do are switch moves, use moves which have extremely powerful secondary effects and increase the health of the Pokemon.
Dynamax gives the flexibility to sets such as Banded Sneasel, Specs Galarian Mr Mime (G-Mime) and Scarf Haunter to not just be effective Revenge Killers or Wallbreakers, but gives them the additional agency to become effective sweepers as they are all able to increase the power of their moves due to Max Attacks. Not only that but Dynamax also gives added bulk essentially filling the the two main drawbacks of using an Choiced Item.
Dynamax’s interaction with Choice Items is something which I think limits skill expression and partially removes the risk of using Choice Items in the first place. Probability management is part of the game and I think Dynamax takes some of that away as more often than not Dynamax favours the more proactive player of the two. I think this point is often overlooked as most people like to tunnel in on the combination of Eviolite and Dynamax on bulky sweepers being very powerful, but Dynamax is extremely flexible and its synergy with most items in the game make it unhealthily polarising in the NFE tier.
Dynamax and Teambuilding
Teambuilding has become significantly more restrictive with the introduction of Dynamax for two main reasons, Dynamax is an extremely powerful offensive tool and therefore nearly all Pokemon are unable to check a Dynamax Pokemon without also using Dynamax. This forces the metagame to revolve around Dynamax, the best Dynamax abusers and the best Dynamax “checks”. Whilst on paper this would almost always result in a Dynamax one for one trade, Dynamax has shown to be very favoured towards Pokemon with setup moves and benefit proactive play more than reactive play. The nature of Dynamax is that it is very unpredictable and which limits the amount of viable Pokemon.
What this means is that Dynamax has caused teambuilding to be extremely linear and the meta has become a few Pokemon with setup and then support Pokemon. This can be seen with Rufflet and Galarian Farfetch’d, which would both be decent threats without Dynamax but have there issues of speed control, and accuracy specifically for Rufflet being fixed with Dynamax. Other Pokemon such as Diglett, Galarian Linoone and Roselia are common support Pokemon which set up hazards and let setup sweepers have an easier time setting up. Almost all teams on the ladder have followed this similar style of teambuilding.
I firmly believe that Dynamax restricts the flexibility of what Pokemon can be used effectively and limits the impact that teambuilding has on the game. It is extremely difficult to prepare for the offensive threats because even the 7th or 8th best Dynamax abuser need to be prepared for as Dynamax makes any decent Pokemon extremely potent as long as it has setup. I think that banning the best Dynamax abusers (Rufflet and Galarian Mr Mime) will not particularly target the issue of teambuilding as the next best alternatives will be used instead and most notably Fighting-types and Haunter will significantly benefit from the removal of their offensive checks.
Dynamax and In-Battle
Whilst I’ve already touched on it briefly before in the teambuilding section, there are really only two ways of dealing with an offensive Dynamax which is defensively dynamaxing and using stuff like Substitute to stall turns of Dynamax. The latter is pretty much never done on defensive Pokemon whilst the former is problematic as Dynamax has proved that its benefits are favoured far more towards offensive play than defensive play. Dynamaxing defensively is much harder to capitalise on also tends to mean you lose far more tempo than the person who dynamaxes offensively.
I also believe that Dynamax significantly limits the different ways you can win the game and instead forces every match to be centred around how Dynamax are used. I think this is extremely unhealthy and somewhat uncompetitive as Dynamax has significantly limited the impact the rest of the game has and forces too much of a spotlight on one decision in the game.
Overall, Dynamax is mean and I prefer we proactively look into it more so we can ban it if it continues to be broken.
Everything about this screams 'I want to ban it and I'll show why' opposed to 'I looked into it and I want it banned.'
While it's your right to think whatever you want, it's clear right now a lot of people see Rufflet as the issue, and not Dynamaxing, in first instance. Can it really hurt then to take out Rufflet and see what it's like then?
Nobody is pretending to be a messiah that knows all, or well, I'm not, and banning rufflet in first instance is a lot safer than looking at banning Dynamax right now, imo. It's a lot easier to unban a mon than to unban a mechanic.
this makes the entire discussion a bit difficult. Rufflet is the issue. Other dynamax mons don't even come close to the threat Rufflet poses to teams. It OHKOs some Ferroseed spreads and OHKOs Shellos, two insanely bulky mons, and casually deals with Corsola. How can you plan to play defensively against Dynamaxing if Rufflet annihilates most defensive mons? It's just not feasible. Give the playerbase, the ones who actually have to deal with all the results, a chance to play the meta without Rufflet, then a dynamax discussion can be really fruitful.
I don't want to overstep my boundaries, but this is my sincere opinion on the matter.
