Warlocks are doing good, ok lets nerf the only thing that they have and didnt changed at all in all the expasion even when they were one of the worst classes in 3s. This may fix the issue
On topic, i can get the point of symbiosis and gateway being cool spells and all that shit
But with those 2 spells blizzard just make the game 50% harder to balance lol, this spells can either be uselees and at the same time gamebreaking.
Imagine you at blizz HQ thinking about how to make every 3s comp have a chance against each other, then you realize that theres 2 spells that can do 1000000000000000000000000000 stuff and change everything you thought before.
