At lower level, ling bane is really easy to win with, because it needs a decent amount of micro from the t/p to win against that. So yeah, at low diamond and below, zerg is really fun.
This changes however, once youve reached a point, where the opponents know what theyre doing. Lets say m3. At this point, you will see, how the difficulty to play zerg rises, when you play against f.e. multiple drops etc.
But its nice, if its fun to you, but plz, dont come up with “zerg so easy” etc, because thats not true. Every race is easy to lesrn, hard to master.
