Keep playing Kaiser?

Just play a zero. They never get nerfed, are OP as you could ever need, are easy to fund due to the weapon system, have complex gameplay and high control requirement, and are available to create right now.

I thought the swapping mechanic was pretty annoying when I last played one, but I'm planning on getting one to 200 anyway for the card and the 3 200 card set bonus. I may stick to it if they grown on me, but so far I haven't enjoyed it much.
