Yeah, unless you have a perfect group every time you run it, it is unfortunately counterproductive to run these fights repeatedly. I say if you don't get it after a few attempts move on and focus your efforts on AK runs (until 8 for the week) and CM runs. Do this while working toward the relic weapon. Even getting the first step of the relic weapon is likely to be a decent enough weapon to let you get through those other fights. If you have full darklight/af2 gear going for titan, minus a weapon, I am sure you will be fine. Kill it once and be done with it.

My beef with this system, you have shit RNG on the weapons, and the other option is run AK something like 65 times to get full darklight... So either it is a grind fest... or it is a grind fest... there is not happy middle. 65 times is just rediculous (imo). I am not at all suggesting they just hand everyone the loot, but if you have cleared the dungeon, making you clear is 64 more times does not make you a better player... it just means you have a TON of time on your hands.
