Thanks for replies.

All of my offensive skills are on R2 + L2. I had to move all my mount stuff to a separate bar a couple of levels ago. I should probably swap Repose with one of my mounts as I think I probably get to use Repose once in a blue moon with a bad tank in a low-level dungeon.

I think what I'll do is adjust my bars just a bit and see if I can get myself to weave Tetra in regularly or get a feel for emergency use as I start level 60 content.
