You do realize that both sides have access to Science Officers? Is it frustrating to get chain held and die without being able to fight back? Hell yeah it is. Is it frusting to almost have someone dead only to have them expose and exploit kill you? Hell yeah it is. Thats the system though, sadly. I'm sure you've done it right back to the opposing team plenty of times.
Whenever you get exposed from any source, there is a high chance you'll be held for 10 seconds. Annoys the hell out of me, too. Expose is a death sentence most of the time, regardless. No need to actually hold us too.
Yup. Both sides do it. It doesn't belong in the lore of Star Trek or in PvP of ANY game. Ask any PvP'er they'll tell you that when a game implements CC is when the PvP goes bad.
And yet there are many games that base entire classes on CC. Everquest for example, or if you want a more recent example how about the "Loremaster" in LOTRO?
CC is only as bad as those who can't deal with it.
Granted Both sides need fair access to that CC. IT's what allows strategies and higher meta-gameplay to be devoloped. Anyone can mash "1" and "2" over and over again, DPSing isn't hard. You can train a monkey to mash two buttons at specific times, that means with enough training you could get a monkey to play ground PvP, he would expose someone, then switch weapons and exploit attack them.
Are you a monkey? Didn't think so.
If you want fairness, how about the fact that despite everything in the game, it feels like starfleet has a much larger chance to get exposes on klingons, while the opposite is not true. In one ground pvp match that unfortunately wasn't very full (it was 3 of us versus 7 feds..Lovely queue system right?) I saw 2 exposes the entire match. But me and my team-mates got vaporized more times then I wish to recount.
And yes, we all had expose weapons, I even checked halfway through.
Anyways back to the topic. CC.
They already have diminishing returns in place for holds, roots, and stuns. I think it just needs to be adapted a little better, and tweaked a bit on durations.
