I can't argue against anything you've said. We push the Templar and Atheon off now every time. We've beat it normal and none of us see the point of dealing with ridiculous glitches or lag time after time while teleporting to just be killed. Between invincible or respawning praetorians, only two people being teleported, or going through the teleported and not being teleported there's no point in really even trying. On top of that the loot is so stupid there is incentive at all. I've been through probably 10 times on one character and still need one piece of raid gear, took me five times to get the first. Couple friends went through their first time and each got a piece, then another their second time. I have three friends that have done it about as much as me and they're full level 30's. You can bust your ass and get nothing, someone can do nothing and get a lot of stuff.
