I started out as GLA/PLD, got lucky enough to join a group once when Odin appeared. Participated in that fight as a level 35 PLD, SOMEHOW managed to NOT die and got 5 mantles. Turned them in for Herklaedi, which ended up being my go-to gear as a fresh 50 PLD. I know I was incredibly lucky to have gotten that and I appreciated the hell out of it.

After a while, the armor started to become neglibile, so I just did roulette for philo tomes to buy Darklight armor (went with body piece as it was the most expensive).

tl;dr - WP is usually the go-to dungeon nowdays. As a fresh 50, you're going to be OP'd by the usual rouletters as they'll most likely have i90 gear. They'll just have to adjust to the difference in playstyle due to that. If they don't then like Crom, to hell with them. Personally, I don't mind helping fresh 50s gear up, but not when the other party members are going to grief them over gear. Not EVERYONE has been playing since 2.0 launch. ¬_¬
