First off, let me state that I am aware that a Job is required for party play and a class is used for solo.I use SCH for any kind of dungeon runs or primal fights, and if I am soloing or doing quest i change to ARN. So here's the situation....
I finally got my SCH to 40 (hurray me) and decided to seek a FATE party in Northern Than. I shouted and got an invite almost instantly. I ran FATE's for a whole day and learning the routine FATE's and what to do and not do to on each one. The next day I go back and join up again with another FATE party, after some FATE's i decide to change to ARN and use my TOPAZ carby as the routine FATE's in North Than do not require a healer to be on point to keep the party members alive.
Now, I am fully aware that the Chimera (spelling?) FATE does in fact require me to be on point as a healer, so, when that FATE pops, i change back to SCH and do nothing but have Eos spamming her cure/buff abilities while I cure members and raise those who fall ASAP to get them back in the fight. After the fight I change back to ARN. At this point, the party leader and a few other members decide to cap-lock inform me that if I wish to use a class then i should do so solo and keep to my job when in a party. Shortly after their educational lesson I am kicked from the party.
Was I wrong in using my class in a FATE party?
