A pug that has troubles with LR-5 is going to have troubles no matter what loot drops.
So it's not pug and I believe you are familiar with it before your tried it.
Changing the LR-5 loot to level 58 gear ISN'T GOING TO IMPROVE PLAYER PERFORMANCE.
I submit to you that it will actually WORSEN player performance, encouraging people to overgear instead of improving skill and strategy.
Most of the players need columi to beat it, especially pugs
It's not a challenge, a FP's drop should give upgrade to most of the players who can do it rather than some elite players.
How about this, the skilled player is rewarded with a LOT of usable loot upgrades.
The mediocre player is rewarded with FEW usable loot upgrades.
How is this not fair?
