The last few days some friends and I have been playing around with our classes in endgame.... Ok, yes there has been some trolling (all of us Flashing mobs in ST) but at the same time we've been looking at how the 10 cross class skills can work for you.

As a THM, I have been finding the following rather interesting:

Raging Strikes, Quelling Strikes, Virus, Physick, E4E (these are the standard BLM cross class, no reason not to keep them)
Internal Release, B4B, Convalescense, Aero, Stoneskin (additions)

Aero is a nice secondary DoT, usable while moving and for Fireweaving. Convalescense is great mitigation (especially with B4B up). IR and B4B are great when added to RS and can be weaved further on as they have different cool downs.

From the limited experience I have with it so far, the single target dps is rather impressive and the added mobility is nice.

Half tempted to make a serious topic about it and see if people would be willing to test the setup and rotation.
