A: nasty horrible idaa, but thanks for sharing.
B: you would think that the NIN would appreciate some help? if you see someone soloing, ask them if they would rather join in, crush the mob quickly, get the drop he wants (if he popped it and he would have killed it, this isn't over the line, he would have gotten it anyway), and then continue. It saves time, both for your alliance and for the person soloing
C: a lot of people don't like the fact that abyssea isnt instanced, but i DO believe that there should have been an abyssite or atma somewhere along the way towards the end of the main quest line that removed the time limit on Abyssea, especially considering there isnt *** all outside of abyssea anymore. Waiting in a zone with no time limit isn't as soul-killing as watching your TE's or Traverser Stones tick away as a NIN or DNC takes off 1-5% HP every minute or so on an NM.
