I found the saber styles to be in JK2, although interesting, annoying. Especially considering that JK3 will contain RPGish elements, instead of having the regular style "fast, medium, heavy" stances they should use the 7 Forms of saber combat.
You start with Form 1 and get 6 fairly soon. After that, you can somehow try and specialize towards the different styles. 7 of course being near impossible to master.
If you read carefully, almost all of them do have advantages and disadvantages (balance in multiplayer).
Something like this:
1 - very simple. No points required
2 - effective against blocking and attacking sabers, but can't deflect blasterfire well
3 - high defense, terrible attack
4 - lot's of combos and moves, but some of these attack types leave you vulnerable
5 - heavy damage, but sort of sluggish
6 - The Jack-of-all-trades stance. Not necessarily great for anything, but its overall effecient.
7 - Cost a ton of points, controls and combos are difficult, etc. But it is unquestionably the best stance.
What do you think?
