About Alistar...

So recently I have been finding a lot of success with and i have been performing over consistent with him and this has led me to a discussion of wether alistar should be tweaked or nerfed. If riot is listening I think they should really look at his ult and the lvl 6 power of it. Maybe scaling the damage reduction so there is less early due to the sheer power of his lvl 6 tower dives. As always this is my opinion and maybe alistar is not strong in their eyes which is fine but I just don't want him to be nerfed in the wrong ways causing multiple nerfs when they would have only needed one.
