Most complex tank class?

[lostclover]

I don't think any are super complex, but I'd say Shadow Knight.

For tanking, you usually pull with an arrow, snare, throw in a lifetap and you're fine on agro. But SK's also have feign death, so the complex part of EQ is something you can learn to master: Pulling.

Warriors are very basic, like you said. You really gotta like collecting equipment and clickies.
