But the point is that it doesn’t matter if you “game” the system like that. The contract was to remove a corp from a region, it doesn’t matter if they leave voluntarily or because they lost too many ships. If the CEO of the corp to remove makes an alt corp, claims the contract, and moves their corp out of the region to collect the payment then those players are still out of the region and the issuing corp’s goal is accomplished.
That said, this isn’t going to fix anything. The problem with war decs is not the mechanics, it’s whiny carebears who feel entitled to opt out of PvP entirely*. No war mechanic will ever get them to fight because fighting is unacceptable. It’s just unfortunate that CCP has gone soft and abandoned their “go back to WoW” attitude in favor of pandering to people who don’t belong in this game.
*Just witness all the whining and crying over war corps declaring war on everything and camping Jita. Trivially easy to avoid if you just stop flying into Jita, but whiny carebears won’t accept the possibility of having less than maximum ISK/hour by having to use a different market system. Nor will they bother to do anything to protect themselves, preferring to undock easy kills right into the waiting fleet and then cry to CCP when they inevitably die.
