Yeah, because that always goes over well for them...
- There are still threads to this day where people complain that the new Sion has "no personality" and they "miss the old Sion," and they think that his "hybrid kit" makes for "varied gameplay" when really his original kit and design was pretty trash. Now, he's actually balanced and people hate him again because he's not "OP" anymore.

Since the Juggernaut update, at least one of these champions, if not more, are banned pretty much every game I'm in, and everyone complains about them being OP. Garen in particular I find is damn near unkillable now, which is horrible. Pretty much everyone on the list is STILL BROKEN.

Her rework is actually good, but no one really says anything about it because no one really cares about Ashe to begin with. She didn't become super OP, so a lot of people don't even remember that she got a rework.
Are you starting to see a pattern here? Either reworked champions become way too OP and people complain, or they get nerfed a little too hard, and no one cares about the rework. Riot has no actual incentive to rework old champions from the community's standpoint... I would much rather they get on that Rune system rework anyway, or a replay system... yeah, Riot has a lot that the fans want them to make, so let's get the big things out of the way... Some champions can sit and stew in obscurity for a little while, imho.
