How can you tell a bad tank?

[Forever_Learning]

I like your comment regarding CDs. I did the Vault yesterday for the first time as AST, and it was wipe city with a DRK tank. I felt I had to do my entire arsenal every pull (lightspeed, you name it) just to keep the tank alive. Eventually, a DPS quit, and so did I feeling like the worst healer in the world. I get now I should have bene 2 instead of bene 1. I was determined to persevere though, so I went right back into the vault. I will learn to be the better healer!

Get another DRK tank, but first thing I notice when we pull - so many extra things light up beside the name when the pull happens! Health, instead of dropping like a broken faucet, only gradually going down. I throw our gravity, all is good cause tank isn't dropping like a rock. We do the entire dungeon with no wipes, I was still traumatized from previous tank, so I was scared to DPS - but it made me realize so much of the issue in the previous dungeon was the tank.
