Yeah but one person would be there. Seems good enough to me.
But then there is the whole.. how it'd be way to easy to buy giatns if everyone could pool their money when each just had 2k. It'd actually reduce depth there.
I really think it's fine how it is now, honestly. Just like I said.. 1 person buy the first level, another buy the 2nd, and it's sort of the same effect.
