lets compare sereval skills
Ein Sof from kabbalista :lv5 +100%max HP, lv10 Ein Sof grant 200% max HP just like before.

While Rune of giants from rune caster used to give +100%Max HP and now after patch it’s only 20% and it needs 4s to cast and also it cost material, it’s ok if it has only these restrictions,the problem is after getting this buff one can only use skills of wizard and rune caster, all of those making it a useless skill.

and another skill :rune of protection also needs 4s to cast and cost material. lv5 has only 50% immune to debuff(not even as effective as 2 +90 SPR bracelet before the patch).,
oracle is rank6 as well,and it can perfectly immune to debuff,.25s CD for 10 hits and almost make it last forever and won’t hit the limit.



(unless it gets capped :<)
