I just started FFXIV a few months ago. I am a casual player. I prefer to tank or heal. I now Q as DPS because of speed runs.

Speed Runs Suck
I don't get to learn the fights.
When tank I spend the whole run fighting for aggro.
When heals I spend the whole run panicking.
When DPS I just hope I'm not mucking anything up.

To avoid this...
When tank I say that I'm new.
When heals I say that I'm new and when the tank pulls to much I ask that he pull less.
When DPS I flail along til the boss and ask if there's anything I need to do.

This has not been working, and I would like to tank more.

I have just been avoiding random Q's: but, sometimes I need a run for the main quest line. I am looking for suggestions about how to address these issues in a way that will work. I am not used to the arbitrary hate of new players that I have been experiencing in FFXIV, so I assume that there is something I am doing wrong when approaching the issue.
