Yea, I'd just outright hax items. As for the lowering and increasing of the general power of moves, I believe we'd just leave that up to intuition. Since this project is already steeped in arbitrary decisions, I see no reason why we can't trust the intuition of various experienced battlers.
I do...and the responses in this thread so far are indication enough. It's difficult enough to get much of anything close to a consensus in this community on actual competitive pokemon, where the goal is at least supposed/expected to align with an ideal that is common to all battlers, Smogon's Philosophy. With "your" ideal metagame (which I'll get to later), many will disagree on the various parts of the luck in the metagame that you would like to tweak, as has already been demonstrated in this thread. At once one can see that the solution won't be "ideal" for everyone who likes a little less luck in their battles.
Again, this would be a modded server in no way related to the official server or the official Smogon server. There really should beno politics here, as if you don't like the idea, it doesn't matter, as this will never be forced upon you. Like I said before, what I want to do is take what is competitive and appealing in Pokemon, the preparation team building part, and maximize the appeal of the battling part myself and with others in order to create my ideal metagame.
You do mean "our" ideal metagame, right? I think you did, but on the off-chance you didn't, realize that there are many different appeals to different people who still greatly favor skill to luck. Like, I think average damage should stay the way it is, because I think it's really not that big a deal. (And I can use the same "I was a danmed good competitive battler" argument you did, for what it's worth.) You feel that 90-95% to 100% may be better, and that "we" would get to a better answer by testing...but you also admit that this is entirely arbitrary anyway so how would you or anyone even know what to be looking for in a test? If anything, agreeing instantly that 92.5% all the time is the best way to go should be what happens if anything, because everything else besides keeping it the way it is is unbelievably arbitrary in theory and more unbelievably hard to "test" in practice.
For moves like Fire Blast, Thunder and Blizzard, I believe the status is somewhat "expected" and should therefore remain, but that's obviously arguable. Moves like Lava Plume are definitely expected to inflict the status, so I also feel they should remain.
Honestly, what? Why is status more "expected" on moves with lesser accuracy? Fire Blast and Blizzard have the same 10% status chance when they hit as do their more accurate but less powerful respective cousins, Flamethrower and Blizzard—only Thunder has a 30% status chance when it hits. Were you under the impression that the status chance for all three were 30% (the only one that was 30% in RBY was Fire Blast), or do you for some reason think that since they have higher base power they should be "expected" to status more? I hope it's the former, because though I realize that this is supposed to be a discussion, the mere possibility of arriving at many of these changes "arbitrarily" kind of defeats the purpose of creating a ideal metagame for everything who favors skill a lot more than luck in "pokemon". Not one person is going to agree that anything "we" decide on is universaly ideal, which is closer to the way everyone regards competitive pokemon in the first place when you think about it.
Lastly, I've posted about this before, but those of you likening pokemon to poker should realize that they are extremely similar in that they way to combat luck is to see both as long term endeavors. Nobody cares if your Celebi got frozen by an Ice Fang on the last turn by a 20% Gyarados. It's one battle. Similarly, none of the actual good pros complain for more than like 10 seconds, if at all about one solitary bad beat like their set of aces losing to a backdoor flush in a tournament, because they know that they game is 99.9% skill in the long run even if one could argue that it's 99.9% luck in the short run. The same logic could and should be applied to pokemon, even if pokemon is only something arbitrary like 95% skill in the long run, because it is true. The best battlers over time, over weeks and months on the ladder, are proven by their skill, nota few random instances of luck, which goes either way over the course of time regardless.
And lastly for real, I will remind you all that, aside from my prior experience with competitive pokemon being more than enough to let me sound off on this, and even with my admission that I would favor a game that highlights skill more than luck and that I still love theorymon, I have played the Battle Tower seriously for something over 3,000 battles going back to Emerald. It is a stated fact from a Nintendo representative on Emerald that the "unbelievable hax" that people who play the BT realize/complain about is actually by design, because it "makes the game harder".
I underline this only because it shows that the only pokemon battling I care about right now by definition has a lot more hax than actual competitive pokemon, so there is reason to believe I would either hate hax more or not play the Battle Tower or both. And, further, to aspire to play on the server that is suggested in Aldaron's proposition. I don't though, because besides the fact that I recognize that competitive pokemon is a game of skill in the long run (and the move bans and tier changes we make do actually favor skill, let's not forget) "idealism" is only in the eye of the beholder and I don't think I'd prefer a game with different ideals when all we've done so far with the actual competitive metagame is to make it more based on skill in the first place.
