Combatwise I will have to say none altho some specials were broken and needed to be fixed. What most ppl didnt understand about Pre-CU combat system was no single proffession other than Jedi ofcourse was stand alone sufficient. Combat proffessions were mainly seperated into 2 categories being defensive and offensive. The system with 250 skill points allowed ppl to make a template of their own to suit their tastes and combat style and still be quite deadly if they know what they are doing. The FoTM templates are actually an undeniable proof to this. The constant whining becoz ppl wanted an easy I win button and not being able to understand how to work their proffessions finally brought the dramatic end of the SWG we all loved.
I picked rifleman/TKA not becoz it was the best but it suited my style and my nature. When i checked for the first and last time Rifleman forums everyone was whining for something yet it didnt stop me pickling it up and mastering the proffession. Even tho the proffession was thought to be superior how many rifleman you can remember who were deadly, not too many were there. Spyff was the only other rifleman who were at par with me. He was my tutor and i learnt a lot from him. The other good rifleman of the server were not too many aswell, I can count all of them here, same with every other proffession, there were stars who knew their proffessions and the rest whiny crowd who picked proffs just coz some other guy used it well. When Zhorx decided to show how strong swordsman was ppl argued with him and then when he showed what a good swordsman can do, it became an other FoTM template.
When i returned back to play Thehoodedone there was an other smilar argument that jedi was inferior against melee classes which was wrong, it was all about ppl not knowing the system well and then complaining.
