As if poison spell didn't destroy CC diversity the first time, the new poison spell being able to kill loons/valks without even pulling them is just ridiculous if the troops aren't moving. I think a simple fix would be if the troops in the poison cloud were just standing there they would walk out of the area of the poison, but would stay in if they were actually engaging troops. This would force some skill in how poison is deployed and the pull rather than just activate CC troops and auto kill them unless they're a dragon/golem/hound, and actually bring diversity to CCs as loons/valks would be viable again.
