AFAIK the intent of the change was to make the animation match the particle, but of course the gameplay impact is important as well. I can near-guarantee that we'll rectify this.
Hey guys I want to bump this with a bit of new information:
If I wasn't clear in my first post, I'm not promising that we're changing the ult cast time. However, we are still aware that this nerfed Xerath and we don't intend to nerf Xerath.
Thus, we (probably, nothing is ever 100% certain) intend to buff him, but it may not be just a revert of the prior change.
