I've played on some other servers that removed pool limits. It's really not all that. If we remain in the current climate, where we're still uncertain how powerful we want pools to be, this would be fine. However, going through with this absolutely would limit our ability to actually improve the pools into being more effective. Right now, if you went and spent your power picks hoarding the "best" powers from the pools, you wouldn't have a build at all. Make the pools stronger like some want though...and this would likely become problematic. So, depends on how you want to move forward.
