As a rear Admiral , I believe I am\ qualified to make this suggestion.
Personally I found leveling from the start up thru commander 7 or so fun and enjoyable. however from there on I found in somewhat tedious to hit end levels. My idea is do some raidisodes like the rear admiral ones, (infected etc.) but for lower levels. Not sure what the rewards should be, or even what kind of difficulty, but it was a thought I had when I was playing last night, and I though id mention it.
mqybe some sort of extra special loot, like a higher grade mark item, u can have 2-4, u get a 5 or something along those lines. These items would auto bind of course.
