In many warzones, sages and troopers are seriously the most over powered class. It is almost impossible to kill one head on at level 50. Most of my server's reps are sages and troopers, so we have a hard time taking them down, with a balanced team. Sage bubbles seem to be more effective than sorcerer's and the trooper can take a lot of damage and still kill within a certain time. They need to be nerfed, due to the opness.
I would also like to bring up, is that, on my server at least, the republic seems to get champion gear handed to them over night. It seems unfair that we imperials have to work our butts off to get that gear, and they getting it handed to them. I think the gear needs be nerfed to, or make it more accessible to both sides equally, becuase we can barely kill, mainly troopers and sages, because they are decked out with all champion gear.
Also would like to bring up the daily quest for armaments. I know it was intended to be an all out war on ilum. However, doing a daily with the fear of getting jumped by five republic op players, is kind of unfair. However since it can happen both way, it's fair? Not really. With the new flood of 50's joining the pvp world, they need a chance to get the pvp gear. I would suggest to make the armaments spawn at the northern and southern assualts. So they can get daily done with a, slight, fear of being attack.
