1. When a similar situation led to the Sith War just a generation ago...such a vicious war would lead to darkness, not to mention Revan's brutal, coldhearted tactics.
2. Revan certainly avoided this trap. And as for the Clone Wars...the Seperatists were being led by a Sith, both inside and out. The Jedi had to fight, to spare suffering and stop Dooku.
3. I was more going after Revan there.
4. The Miraluka weren't anywhere near gone after KOTOR and there's also very little to support the loss of techniques. Thanks to the holocrons and still living masters, things were well passed on. PAlpatine supposedly studied Sith holocrons thoroughly and Yoda had access to Vodo's. It is totally incorrect to say the Sith don't give their knowledge to every apprentice. Palpatine/Plageuis thing....we don't know if Plageuis could do all he said he could. Palpatine learned how to influence midichlorians from him, but saving people from dying? Saving PEOPLE HE LOVED from dying? A blatant lie. Bane made it a point of teaching everything to the apprentice. Bane's line got stronger with every apprentice. He taught Zannah literally everything he knew, she developed things of her own, taught all that to HER apprentice...and so on and so forth. each apprentice had the strenght of the master with a bit more. This was in the Dark Side sourcebook, I believe.
Kit, Agen and Saesee...we've seen them in action and they are anything but slow. Agen's skill put Mace on his guard and Kit was so fast he could hardly be seen to move to Obi-wan. There is nothing to support the Sith got weaker...in fact, there is everything to support it was the opposite. the ROTS novelization sums it up completely and for the EU, that is a perfectly valid source. And in KOTOR's combat, we do see Malak fight...he's hardly fast. And decided with a saber? No way, Sidious would outsmart him there...or destroy him with the darkside. ROTS era Sidious can tear apart a ship with the force or kill a small army with lightning...without even exerting himself. And who says Malak's supreme with a saber?
