No, it gives Valour Impact double the hits and gives Soul Aegis double the duration (and CD) as well. But BaltaelSynch is indeed the main drawing point; it's a very powerful skill, fantastic for obliterating quest mobs quickly.
And TK is definitely a very strong class, but there is no "strongest class" other than perhaps DmK. TK is a hybrid, having great offense and defense, but it's not the very best at either of them so whether that's "better" depends on what you prefer to fight; defenses in particular are barely needed in most fights, and only challenge fights will need more than Asc's standard defenses for example, while Asc can do multiple times the damage of TK. So if you're not looking to fight Extreme Hard Mode challenges, any class with better offenses is going to be "better" at that moment. Since most people don't care much for challenge fights and just want to kill things quickly, there are other classes that will work more for them.
Defensively it's in a better situation, since it has a loopable blind which means it's virtually immortal against single enemies. However it's at a significant disadvantage compared to some defensive classes against multiple tough enemies (not like that happens much anyway though), since its shield has a long CD of 9. So in the theoretical situation that you're fighting an Extreme Hard Mode challenge with multiple enemies, you may need something with better defenses to survive, in which case those would be better at that moment.
Edit: Aww, ninja'd about Baltael. And it is 2 turns, but that includes the turn that you use it and do 0 damage, so you only get 1 turn of applicable Boost.
Edit x2: Actually nevermind, turns out the Boost is 3-turn and the shield is 2-turn. So you can indeed have it boost both Being and Touch, though that doesn't change its ranking any. :D
