This patch is looking great. Also really enjoy the format and reason for everything, makes it easier to follow. Fantastic job.
Most changes are looking good, agree with that
but the gas cap
I dont see the point of beeing limited to 2 ghs, and agree with eyyo here...
as for the ghost argument, ghosts get rly energy efficent late game so they can handle a lot of heroes with emps and cheap snipes if played well. The only hero that gets problematic imo is the double ultralisk which will require several snipes each while wrecking havoc on the enemy army. In this case you could just reduce the armour scaling of the unit, making it so that it can be hurt by armies as well, or limiting it to 1 per player.
And if you limit gas to 15, in the very most games that changes nothing, its really rare to reach that, but whats the point of making the gas cap then? It allows way more heroes than Ghost/Nova can handle by themself (the idea behind that cap) and needs to be answered by more heroes yourself. So if it is 15 or higher why the gas cap at all? And in a few rare situation it still can have an impact, something like 100 or no gas cap seems more accurate, and wont hurt anyone.
