Edit: i misunderstood that vlad was somehow deemed too strong with sv. rather its mainly that he was one of few who used it
Spanked eGirl1 votesNo... they said only one champion actually uses the spell vamp. Literally Vlad is the only Champion to build WotA. Theyre going to adjust Gunblade to account for the change. So Vlad is also going to be changed at some point to adjust for no longer having the item.
LilxPaprika1 votesoh so its not that it was too strong on him. mb.
its mainly because they didn't make it work with aoe spells. this could have help fixed that: http://boards.na.leagueoflegends.com/en/c/gameplay-balance/TaXPYTao-spellvamp-100-scale-on-aoe-but-with-100-cap-as-thoughwas-singletargetoverlap-w-current-equation
JackMcSnipeyz1 votesNo, they said they couldnt find a balanced way to change it for all mages, and that only vlad uses it. Not that vlad is the reason they removed it.
LilxPaprika1 voteseven if half the mages can make use of it isn't that enough?
doesn't synergize with every adc either.
for the other half just give them some kind of % regen stat out of combat that scales off AP like warmogs scales off hp.
