You know, it's kinda sad that every time i see a poll on this question it's an overwhelming amount of people who want to bring the old system back.... and i can bet, most would want a modified pre-9 system.
Implement the armor changes teh CU brought, the health/buff changes, also implement class specific defence to cut down defence stacking, and then put in some medic changes so that the more medic you have, the less defence you have over all(to make all CM and MD templates be mroe supportive templates). If they did that with a pre-9 game, i think most people in this game would be happy.
Leave jedi powerfull, but allow more BH to take a mission for higher lvl jedi. For example:
0 - 50,000 bounty = 2 BH max.
50,001 - 100k bounty = 3 BH max.
100,001 - 150k = 4 BH max.
150,001 - 200k = 5 BH max.
200k - 300k = 6 BH
300k - 500k = 7 BH(this would be FRS only studff
)
500k - 700k = 8 BH
700k - 1 Mil = 9 BH
1 mil +(Jedi Masters) 10 BH
Make it so that BH must be master BH to hunt jedi, and so that to grab the same mission, you just have to be in the group with your fellow BH(so 2 BH in same group when taking 50k bounty means they both get the mission) Then they can remove names off the terminals(leave ammonts on) and no griefing possible. THen just make it so that Jedi at those respective levels can take on that many Full template BH in a fair fight(obviously BH will try to get an advantage and so will the jedi)
A combination of Pre-CU with Post-CU systems would un-doubtably be possible, and be in my opinion, what most people playing this game want.
