Anything that requires a login in this way, meaning you have minutes to reload or get whatever job done, seems to be pointless and a penalty against people that have jobs or school even. Like Nightdawg said, could care less about the time, that is fine, the resources, ok no problem, just make it so it can all be loaded at the start.
Ninja edit: I would be ok with a 24 hour reload time rather than 12 so that it could bve done when i play. *ducks*
