1.0 was fail in so many ways it wasn't even funny.
2.0 has no fails from what's been shown. aside from people might complain fighting is to slow or to fast or whatever.
even if 2.0 is released *to early* it's still not gonna flop like 1.0 did, cause it's much more polished by default.
Many games are not perfect at release. And some people gonna whine and quit, even if game is delayed to be polished further; and we don't care about those people anyways. some people are gonna stick around even if it's not delayed further, because any small issue that's still there by given roadmap, will be fixed after release. And any such issue won't likely be very big.
They will listen to peoples ideas and such ofc, but they aren't gonna make any big game changes, that will delay the game. And by phase 4 the game will be basically finished anyways, with all the alpha/beta feedback changes.
I think 1 month/phase is way to much no matter how you look at it, so i don't think there's gonna be a worst case scenario or worse, with july/later launch. But i'll consider OB, and 1.0 chars to be launch anyways
I can see that happening in april-may. Any tweaks during OB doesn't matter, it's not gonna *delay* the game anyways, cause for all purposes it's released already. Only problem would be if they had to wipe cause issues with 1.0 migration.
I don't see any reason for delay after beta either. Most games release right after OB.
