Warring is broken for many reasons, namely the strength of certain spy ops/lemmings/first strikes too powerful/restart changes needing adjusting/humanitarians and gdi hiding.

I'm actually a fan of this change since it weakens the losers who resort to suiciding, although it seems buggy in it's current state (which is to be expected). There's been a few instances of civ returns rollercoastering for no apparent reason. I know I reported one directly to martian.
