The instantaneous death bug should be top priority, it occurs in two forms 1: You are fighting a mob, taking no damage and bam you are dead. 2: You kill a mob, are a full health and then 10 seconds later you die. I cant possibly calculate the amount of experience I have lost due to this. Its made me virutally stop playing for the past week.
Treatment kits and first aid that you cant use until you rezone even though you are not under attack. God help you if this bug strikes you when you are deep in a mission and hit with a DOT. Not being able to target MOBS through vine doors when they are open, this has been there since day one. Total BS esp if you are an NT or other first strike necessity profession. Also I got hit with this one the other day not being able to get out of my car and then hit with the spontaneous death bug with no mobs in site. Simply awesome. Missions still suck, up the cash reward already, I still have to spend 20 mins to get to my mission and am now stuck with 1/3 of the reward. Spectacular. Im sure these are just the tip of the iceberg but I can only report it as I see it as an NT.
