Good summoners already spammed ruin 1 and 2 with no mana problems, while having thunder up. We lost a main dot in our rotation with nothing to fill its void. Wow I get to spam 1 more ruin or ruin 2 instead of having a dot up that does the dmg of 4-5 ruins yea not a nerf at all.

I dont know if the op dosent know how dots work or not, or if he knows math, but dots allow us free time to do what ever we want while doing dmg. This nerf is big. Expect a 10-12% decrease from them.
