Because I don't want it long term. And picking a fight with one person usually involves their entire club and allies and people not even relevant to it... Pretty simple..
Pretty sure no one's stupid enough to sell all their tuts and bank the $$. Specially people with over 1m tb like myself.
A lot of people would use the war as a way to make $ and as an easy way to get rid of any tuts they dont want.
I'd include a new rule tho... You can't be sp or you get sf'd even when out of war... To stop ppl from just joining to get tuts hired and sp'ing.. Lol. And maybe a "you have to be active a minimum of X amount of hrs or get sf'd after war" kinda thing... lol
