Alistar got his art redone..

Is there any real reason he couldn't have had some new VO lines added? A recall animation (aren't those standard now?) Some love for headbutt? It gets cancelled my basically every movement ability in the game.. Cancelled like.... no damage or knock back. Or at least some changes to trample (Because it's pretty terrible, especially as straight tank Alistar). I just wanna see some more beef on the Rift, and I was curious why Ali kinda got left out with the redo.
