LMPQ is amazing EXP for 100-130 with the help of one or two funded friends. I had a 20X Kaiser, not used to the PQ or with very high damage, basically getting tickets on his own. He got 212 tickets, and my level 100 Dark Knight jumped to level 111. Another 200 tickets and I'm level 116. It took the Kaiser a while to get the tickets himself, but I've also had a 4-person party where the other level 200+ character did 2m crits like me, and we could rack up 175+ tickets and be in room 16 in about, oh, three minutes a run.
I haven't tested Dimension Invasion for EXP as a 14X or 15X character. As a 206 Mechanic, I'd get like 2% a run, but there's no way to speed up the spawns past a certain point, so most of the 8.5 minutes is spent going "laser laser wait, laser laser wait, laser laser wait". I get that it's not intended to be challenging for characters with a 200K+ range, so that's understandable. Though the boss at the end, if you get to it, does actually want that sort of range. I've only seen Blackheart twice, and both times I killed myself on the DR because I didn't know what the animation looked like.
