It's happened more than once where someone was slaughtered and lost everything on them because someone unexpectedly killed them and they couldn't teleport away due to combat mode. I propose that combat mode should be initiated only if you hit someone, not if you are hit. This takes the advantage from the tp killers and wandering killers without making things unfair. Another suggestion is that Titans have the inability to enter /god while in combat mode. I know it's been suggested before, but it really does make things like PvP frustrating.
That means that if a leather armoured guy sees like a decked out guy and he gets hit, he can just like/warp away. No support btw, combat mode doesn't rly matter bcos the Ppl who are getting rekt just need to /spawn and they get away. That simple.
