so i dealt over 300m damage on one raid then on another only 40m but got essentially the same xp. With that huge of a difference i think something might be wrong with the payouts this raid, dont remember them being this close together no matter the damage dealt.
It's always been like that - one time after I got more XP from doing 5k attacks on a raid than from soloing one, I kept a record of the XP reward at the end, and the only times I got significantly higher XP reward was if I had done more healing actions than attack actions
