Hmm, personally, I would put the level 2 point into Goop, as you can then make use of the slow, ignition damage, and continued burn. In the actual gameplay, it will allow you to kite enemies when you're fighting them, or to just plain slow them if you're running away. This is particularly important if there's an early invade (not a bad idea with Skaarf), or if you're being harassed in lane. It also allows for wave clearing. Other than that though, good guide. Have a vote :D
