The Alistar buffs aren't going the change the fact he got gutted over multiple patches then no buffs
Seriously his healing is fine it's the fact that he does absolutely no damage since you have to cancel your W to do the combo and then on top of that he has a whole season of nerfs on him, less damage reduction less damage.
Why would i want to play Ali anymore when Zyra and Malz and Lulu have more CC in a single ability than he has in his whole kit and they don't have to wait 5 seconds on someone to get a 1 second stun.
Seriously he needs to do a bit more damage so people can't just ignore him or have more CC time because until then he will just be a champion whos peel is mediocre, engage is ok at best since you blow your load then sit around uselessly for 7 seconds compared to many other tanks and supports and to top it off just has very low tankyness now due to the ult nerfs.
