What gets you killed the most in Defiance?
Other than PvP, the thing that kills me the most and quickest is blastpods. Those damn things do 75% of my 17xx shield per shot.. the thing is they fire 3 shots and there's often 4 or 5 of them around at a time. Ark fall alone in waves that include blastpods... most of the time you'll be running in circles killing them and doing no damage to the crystal.
Another normal (non-bug) thing which kills me is those players who run tankers toward you from behind while you are shooting something else. That or the tanker is shooting them and they come and stand next to you. Thanks guy!
Other than that, re-re-reloading (bug) causes serious issues. Measuring that you will just about survive if you reload now and shoot immediately .. only to have your re-load repeat and consequently your estimate was wrong, you die.
