Does GMS need the BB patch ASAP?

This. That's not to say that, like others have mentioned, the game will all of a sudden "be equalized and hard again." The game was pineappleed the second the potential system was released. At least the Big Bang patch smooths out some of the glaring imperfections a bit.

But only a bit. PD/MDRate is the only safeguard I see that can truly help neutralize/balance the insane damage of all players, and even that is hastily thrown together and poorly applied throughout mobs. For this game to make more sense, all normal mobs should have rates between 30-40, triple/quadruple what they are now, while bosses all have rates 50+, with PB at 75. Even then, that's asking to create a whole new system just to fix something broken in the first place. Why not go back and fix the original problem?

I guess the bottom line is this: remember when we could glitch PYPQ to get the 400% damage buff outside Ariant for an hour? Everyone was abusing it trying to do the best pomegranate in town, like downing PB, which never occurred. We've now killed PB a good couple of weeks into the potential patch. That should tell you how OP'd and poorly done the system is.

I don't really see how the revamp fixes the imbalance of the potential system. All the weapon damage formula changes just involve changing constants and shifting them minorly so that proportionally, there isn't much difference. Defense rate doesn't change this either since it's proportional, and if it were calculated after regular defense, it would actually give an even worse disadvantage to the weaker characters. There's really not much that could've been done after releasing the potential system other than having damage formulas with something like decaying damage increases as main stat increases (as in doubling your main stat wouldn't be close to doubling your damage as it is now). I strongly agree that the potential system should never have been released though. I had already thought that equipment played too much a role in a character's damage before, and now it has gotten a ton worse, with highly funded (50-100bil+ worth) characters doing like up to four to five times the damage on bosses a character with mediocre equipment would do, as compared to maybe twice the damage before. I'm sure it was even worse in pre-revamp kMS with the double pendants and pet equipment. Also, I don't think anyone was seriously trying to kill pink bean with the pyramid glitch, mostly for fun and experimentation.
