You came here asking for thoughts / suggestions, and then proceed to ignore or even bash the suggestions (which are correct by the way) that were offered. People took the time in responding with the actual skills and rotations you're expected to use.

If you want to keep doing things the wrong way, that's fine--but don't every expect to ever clear any serious content with that kind of attitude. Provoke should really only ever be used for tank swaps or getting back a mob that a DPS stole away (which should hardly ever happen).

Btw, most of the time, if a dungeon gets completed without really any hiccups, usually people don't say anything. Many times a tank receives the commendations because he/she is the one leading the run and setting the pace. Also, the tank's name is at the top of the list, so that makes it a simple choice for someone hurrying to give their comm and get out of the dungeon.

So, my advice? Listen to the advice that others have given you to improve. Your thread title states you do not know how to tank. No, using flash on a boss is not optimal. Provoke does not initiate aggro--it only puts you at +1 over the person with the highest aggro at the moment. Don't ignore shield lob--it should be the first thing you use on a boss.

A final thought ... a person that asks for thoughts / advice / etc. and then refutes or rebukes said advice, well, then that person is a fool in my book.
