Hi guys,
I know it's too late, but as i had a chance to test drive EotE only recently, i'd give my two cents anyway.
The Knockdown Talent is the worst idea ever .
The beauty of the system is, IMO, the possibility of action packed & cinematic combat encounters, with a lot of stuff happening, assuring it's NEVER "roll to hit apply damage" dull.
The Knockdown Talent basically says: "if you don"t have this Talent, you CAN'T put an enemy on the ground". That sucks, as tripping(triping ?) people is a nice, dramatic move which happens a lot in hand to hand fighting scenes. And on a technical pov, it's not a "I win" button.
A much better take, still IMO, would be to add the knockdown effect of the Advantage table (3 Adv cost, for instance), and allowing the character with the Knockdown Talent to use that effect for 2 Adv only (maybe renaming it something like "Knockdown specialist" ?).
Anyway, as i said, my two cents are probably too late, but it had to be said
