I am in a mix of Darklight (Belt, Wrist) AF (Boots, Legs) AK (Chest, Helm, Hands, Ring) and player made (Rest of the accessories) with the Ifrit Weapon.

I won't get into the details of the group that triggered this question, as it is kind of petty and would border on tl;dr status, but suffice it to say, I accidentally offended a Relic+1 BLM and he started actively trying to steal aggro from me on mob #1 of every encounter (or so I suspect). No one died or even took more than a couple hits in the whole run. Afterwards the WHM sent me a tell and told me that he hated me and my "kind". /shrug I will take that all with a grain of salt and try to learn.

I realize Ifrit + a mix of AK/Darklight isn't the best gear, especially if I'm up against a fully DL + Relic+1 dps. I will take the comments of the other group members with a grain of salt and learn what I can from them, but does anyone have any advice on:

1 - What I can do differently in these situations to preserve my reputation and appease people like this.
2 - What are some of the most enmity-effective combinations that you all use when grouped with people who out-gear you by 20-30 ilvls?
