Oh, so sure of that, are you...?
We'll toss that aside for a bit, true or not.
They DID promise a Yorick rework, that then got delayed by YEARS.
They promised an Aatrox rework, and that just keeps getting pushed back in favor of other champions.
They claimed they would be giving Janna nerfs, and then in defiance of the PBE testers warning them, they released her kit in a massively broken state that they had to hotfix shortly afterward due to the sheer absurdity of it.
In spite of that madness, they repeated their mistake with Galio, which shows that they simply do not learn.
They said they heard us and would try to be more diverse with skins, and yet Lux was given a skin in defiance of the fact that she got an ultimate skin only a year prior, Yi was handed multiple skins, Janna was given a SWORD-THEMED SKIN that would have been a FAR better fit for Shen, who had gone much longer without a skin, Fiora was given that SAME sword-themed skin over Shen, even though it was Ionia-based and Fiora is DEMACIAN (and again Shen has waited far longer for a skin), Yorick's first new skin in damn near five years was underwhelming as hell...
And while we're on the subject of Shen, his update was halfassed and didn't even update his voice with the rest of him. Instead, he was tossed to the wayside so Riot could spend more time updating their poster boy Ryze. For the second time.
Riot's word has about as much value as a politician's. Maybe if they actually had the work ethic to finish the things they start and to follow through with the things they say, I'd trust them.
But they don't.
So while I'll be happy if they do finally do something? It doesn't mean I'll trust their word at any point before it happens.
Nor does it excuse that it hasn't already been done.
