When I do duties on PLD I usually start off with 1-2 small pulls to gauge the party if I queued randoms in DF. This is to gauge the DPS output of the party mostly. I've very rarely had issues with healers on big pulls but I have no desire to do a big pull if its going to take the DPS 10 minutes of combat time to kill it. I've never bothered running STR accessories on my tank jobs. Would like to see them improve this new tenacity stat a bit. I stuck grade 5 battledance material in just about everything that could benefit from it after buying a set of verity gear. It made a slight difference but not as much as I would have expected. I might try out grade 6 on another set of gear to see if its more noticeable since the numeric difference I think goes from 12 per material to 40.
If I do a 4 man duty with ppl I know all bets are off and I am pulling EVERYTHING :P
