I've read this guide and some other bits around on the Internet--though some of what was said flew right over my head--and I understand that I should level Desynth on three DoH classes only. I've narrowed it down to GSM and LTW based on my playstyle and the DoW class I intend to play most (BRD), but I'm not really sure what the best choice for a third Desynth class should be.

As for my playstyle, I'm a solo player and not a raider. My "endgame" will probably be crafting and collecting things like minions, mounts, achievements, glamour, etc. I'll also want enough decent gear at 60 to make HW overworld content a bit easier and also to run older instanced content, possibly solo or with a friend, to obtain items for glamour.

Am I on the right track with GSM and LTW? Can someone suggest a good third choice?

Thanks!
