Basically 1.5 hatchery of production, 99 range vs ground and air to defend anything, no larva cost, free vision and speed from creep, can heal own units for huge amount, super easy to use with shift FOR 150 MINERALS AND 2 SUPPLY. In my world this just doesn't look like a proper unit. To fix mass queen madness (both early and lategame) there should either be only 1 queen per hatchery OR limit how far away the queens can go from their hatchery OR disable their default ground/aa attacks and give them enrage ability for 25/50 energy to be able to attack for 15/30 sec.

Change banelings to be similar to the BW infested terran, i.e. when they die they dont do splash! You must detonate them with X button (was that default?) or they must hit the enemy units (1a). Zerg totally requires no micro to fight, this would make them busy. Why did we get that +10 hp buff after all, make it at least justified?
