I don't have much to add to the conversation right now, but I have recently played with both Arcane Blades and Marauders, so I'll share my limited perspective:
I skipped Battle Tactics on my ABs. Not because the tree is weak, but because it didn't match the style I wanted to play with, and ABs have plenty of other talents to invest in. Heh, for my desired AB playstyle, I'd be perfectly fine for dropping Battle Tactics from Arcane Blades. Having it can make them play too similarly to other classes as has been mentioned.
My Marauder
is using that tree, and is relying on it. And not just Greater Weapon Focus, but
all talents in the tree. Marauders may seem an underpowered class (I really don't think they are) because they lack certain defenses, but man can they kill things. Step Up lets you kill the dangerous things first, and True Grit is actually a good "catch all" defensive skill useful for not dying. Marauders
can get incredible Defense too if they want, but my current Marauder is ignoring all defensive skills except for True Grit.

To reiterate, it was one proc per turn
per spell. So, if you have Lightning, Flame, etc., then each can proc once per turn.
