Movie Summary
This is a guide on how to solo Bloodlord in ZG for your mount. Thekal can be solo'd very easily with any combat spec, but Bloodlord takes a special strat for rogues. This will explain what to do for it and almost any rogue can do this with 5 man gear+.
Things you want:
Lifeward
Battlemaster's rage + fel healthstone(I didn't use one)
Rocket boots(most rogues are engineering so should have it)
Spec: 0/43/21 required and the rest of the points you can put wherever you want.
Glyphs: Prep, Evasion, Ghostly Strike
With this spec I was easily able to solo any boss in ZG, except Hakkar didn't try him yet, and some I did not even have to use prep.
Happy Farming!
