Two questions: 1 -if a higher level player eats a lower level player's rig - do they lose XP as if they had been killed by the low level player or according to their own level (ie they commited suicide)? 2 - do tripped rigs open the attack window?
1- Death always makes you lose 4% of your exp, no matter if you're killed by god or by a level 50. 2- No.
