Orgs closing due to "big bags of cash being thrown at them" is very rarely the reason. 90% of the time it is related to burn out, lack of interest or simply real life. At that point, org owners care less about the "big piles of cash" because they do not care about the game, so that cash is pretty much worthless. I have merged several orgs in the past and in most cases i paid little to nothing, the org owner simply wanted to give his fighters a place to relocate and that was it.
Of course I understand that, I'm all too familiar with those circumstances. But I was specifically referencing those particular cases in the past where an org was bought over / merged / closed as a result of a hefty buyout, as I've seen it happen a bunch and it has been quite sad to see. I don't blame the owners who are burning out though as running orgs is no easy task - hell, I'd probably sell Budokai if the right person offered the right number.
It would be nice if there were more bigger arenas and limitations in place so that the richest orgs don't just monopolise them. Also, I personally hate to see perfectly good orgs get bought out by bigger ones for no reason other than big bags of cash being thrown at them. If Pulse was to meet this same fate I'd be terribly upset.
