How do you make a tank angry as a DPS?

No markings usually means "target the monster the tank is targeting". I only use numbers when people are too stupid to figure that out and every single-target dps attacks something different
Now I don't know how well your aoe is developed in that dungeon (depends on if you hit 30 already or not), but since the aoe strength of ARC/SMN below that level is not all that great, it's not wrong to stick to single-target dps as well.

Oh, and the actual fault lies with the healer. Nothing in Haukke normal should be able to wipe a party anyway.

That it so wrong. Im a tank and if I dont mark mobs it means 'dps all of them freely'. Do u think that dps even bother with checking which add is being attacked by tank if he pulled like 15 of them? If I don't mark and loose aggro on any of the add I pulled its entirely my fault. It I mark tho and I see that I loose add out of order to any single-target dps I just let them tank and eat dirt if healer follows my logic.
