And what's the alternative here? Stand by (while an attack is underway as indicated by the flashing?) and watch it be taken, in case it may the same attacker that was just at that last place? That doesn't sound reasonable.
As for spawn jumping... that would mean that you had it capped? or camped? And was picking the camp as they were spawning in? Sounds like an effective tactic for him to up, shoot, tower, spawn in (different spot) so the campers & pickers have to actually search for your location for a few seconds before the deaths. It's actually too much of a hassle for me to do ~ I'd just stay put until killed, then come back.
Sorry, no sympathy back pat from this direction.
