It's like the Vortex, either very good or absolutely awful. And often times completely useless in all MUs, esp Terran.
My issue is Vipers are so late that SH is really the only "New" unit that we have and feels very unbalanced.
The reason this is an issue is because the hydra is still very expensive and situational. Having two major situational units is mid-game is very scary; also considering the Infestor nerf it makes the mid-game that much harder.
While I know Swarm Host + Corrupter is strong vs certain toss builds, it's very weak against everything else.
Anyway enjoyed the beta so far! You guys are doing a great job!!!
