Ok let’s brake it down larva 3 every 30 secs max 15 per hatch.
Thors problem is 10 range vs air, it’s design was counter mutas but range made counter brood lords.
Talk about slow unit.
Corrupters are good but most Terran forget about liberators mass can defeat corrupters. Mix liberators with bc you got army Zerg has throw 10 times that to even stop first wave. Once you mass 10 bc you hyper jump Zerg base and auto win.
To fix Thor make it siege tank speed.
Reduces its air range to 7 and cut its ground damage in half. (The last part might be extreme but it’s does 30 x 2 at fire rate .91
That’s 65 dps at range 7)
No unit outside ultra at range 1 has dps 56.
Archons, tanks, lurkers has dps under 20 yet Thor has 3 times that.
Evening cutting damage in half it still have higher dps then most units.
