No Love for Spellvampers
Right now there is absolutely no reason to itemize spellvamp over other items that provide sustain. Aside from the obvious fact that players only have
as build options--which phases out most AP casters--the few champions that do benifit from it would be better off investing their gold into
or just straight up HP Pool + Armor/MR to stay in a fight. There is very little synergy between items that offer spellvamp and other items which most champions are able to utilize to their fullest potential under the meta that's currently been laid out for us.
I don't claim to know how to remedy the situation but it would be nice if Riot would at least pay some attention to this useless stat; maybe scrap the current items that utilize it and start introducing new spellvamp items that provide more relevant stats across the board, like MR or magicpen, with corresponding kit changes to the few champions who use spellvamp as a crutch for their already toxic self-healing mechanics. If not more relevant stats, tying spellvamp to some wacky, game-changing item passive/active abilities would be just wonderful. Increased healing from DOTs/AOES is also something that should be considered, as should changing the masteries around so that champions who invest heavily into the offensive tree can toss a few point into something that benifits spellvamp-users to a greater extent.
Champion diversity may be growing but our build options are really becoming more and more restricted. Changing the spellvamp items in a way that offers more utility/counterplay would, I think, do the game wonders.
