What I fear is that many people seem to completely ignore the difficulty sliders.
Yep, I think that is true for the majority of players. I'll include myself in their number. I only change the slider when I feel very bored. The battles in STO - no matter what difficulty - do not exactly excite me that much.
Perhaps if they revise the system one day...Especially for the ground battles.
At the moment I'm just happy when they are over. OK, Foundry changed that a bit, as some missions are very creative depicting large scale battles.
