Some guys in our alliance did some testing on NPCs in Black VS Rift Invasions and got the same amount of exp (relatively, give or take a couple exp points) on a Boss reaper each time. Difference margin was maybe 50 exp at the most, which should be substantially different considering the game MOTD says 2x Exp gains in *ALL* invasions. Assuming this includes RIFT invasions, the exp event must not be actually active.
Assuming the event was never active, we've been mislead for months. As an apology we the tib community demand either Battle Royale for a weekend, or activation of the exp event.
