I was thinking about this on the way home from work, and my ideal solution personally would be to have iLvl sync on upper-end content. Speedrunning tactics are easy because you have so much goddamn HP/curative power/damage that you can actually do it, because you're bringing in gear that's 30+ levels higher than what was intended to be worn to do the dungeon.
You can't speedrun a place like Qarn or Aurum Vale. Well, you can try - but your success will be limited. It's because there's a maximum to the power you can bring in with you, which level 50 content simply doesn't have.
