So today i did my low level random Duty finder it only took 4 goes thats right 4 times i had to Que as BLM.

The first tank left because in the first boss fight the healer did not use sprint to kite adds it was the first go on the boss just after we wiped he left.
The second left just at the start of the instance we had all just got to the point where we could talk to each other and we get "sorry g2g"
The 3rd one left in the middle of the instance just before the 2nd boss.

Now I would love to see a deserter debuff put on them with a time limit BUT what about the people like me that got stuck in the instance in every case we had to leave and reque would we get a debuff too I mean i did wait for a while on the 3rd time to see if a tank would appear but the chances of getting a tank are low lets be honest.
