I've been playing and spectating the meta and to be honest I've had lots of fun with dynamax.
Dynamax is an interesting new game mechanic that adds an extra layer of power to battles. Since you can dynamax a mon basically at any moment you really have to think about the best possible situation to do so while taking the opponent's dynamax gameplan into account as well. Many mons can find an opportunity to viably dynamax which leads to interesting choices and matches.
There are different kinds of ways to utilize dynamax:
Offensive dynamax: When the situation looks promising you can just dynamax a mon and keep firing powerful attacks for the duration of the effect. Most mons can do this and it can provide just enough extra power needed to win a game.
Defensive dynamax: Dynamax can be used defensively by allowing your mon to tank a hit that it couldn't take otherwise. This is a great way to stop a mon that threatens your team or is problematic otherwise but dynamax is such a powerful resource that it should be used to cause as much damage as possible.
Dynamax sweepers: Dynamax sweepers are the real deal. They can use a setup move before dynamaxing and then start spamming insanely powerful max moves while also getting extra bulk to survive many hits. Or they can boost stats or set helpful weather/terrain via the additional effects of max moves. Or setup with regular setup moves first and then with max move effects.
Like traditional sweepers they do have counterplay. They need to find an opportunity to set up without getting killed or crippled by something like paralysis and certain mons can stop their sweep, especially ones that are dynamaxed as well. The counterplay is often quite limited though as certain sweepers have potential to be so ridiculously powerful that they can break through entire teams or cripple them extremely, sometimes even very early in the match. This makes the metagame circle around dynamax sweepers quite a lot.
To summarize: Dynamax is epic and I love it. But dynamax sweepers being too strong is a valid concern for the metagame and its development.
