Type of builder

Just a small suggestion:
Make the builders "summoners" instead, that way players can build
multiple towers at once without waiting for the first tower to be done.

I was thinking of changing a few races to be able to build like that. Part of the gameplay is this strategie. You have to account for how long each tower takes to build, and when the creeps start coming. To have the builder a summoner, then it makes it much easier, and take some of the difficulty out of the game. but to have a couple of races benefit if they are already "shitty", then it should be an added ability for them.

yeah build time is relevant, don't make them summon!
