I saw a few people around here mentioning that casters should be nerfed/changed into more of a support role, and I believe Blizzard said this at one point and tried to make mass caster no longer viable. Here are my thoughts, please let me know what you think.
Ghost:
In a support role for sure, though more of them are made than any other caster, no one goes mass ghost until the extreme late game, where I think it’s ok because they are very expensive and pretty brittle. Massing snipe can be good, but just counter by swarming, and mass emp doesn’t accomplish anything that a handful of emps wouldn’t anyway.
Raven:
Never massed, ever. Max 1-2 are made outside of TvT where small squads are sometimes made.
Sentry:
Never “massed” though they are made in larger numbers in PvZ because you really need those forcefields.
High Templar:
Mass templar doesn’t really exist because you can’t stack storms, I guess the closest you would get is templar archon, which is sort of a thing in extreme late game PvZ but there are almost always carriers with it.
Oracle:
Mass oracle is a cheese strat but not viable in a normal game.
Mothership:
Mass Mothership is a PROBLEM!!! pls nerf blzrd qq
Queen:
Queen is only on here by default I guess, mass queen is kinda funny to watch against bio/hellbat pushes but in a mid-late game scenario it just doesn’t hold up.
Infestor:
Used to be overpowered as hell, neural nerfs and infested terran removal did a good job imo, groups are sometimes made to neural a big mech army but mass infestor is gone afaik.
Viper:
Never really massed beyond 5-6.
So yeah, I haven’t seen any kind of mass caster bs since BL Infestor got nerfed, people who think it is an issue, lmk ur thoughts.
