Until pug vs. pre made stops being such a massive miserable experience and pvp becomes popular enough to have decent gamescore matching, I consider STO pvp dead and buried.
There are no good rewards, the system is riddled with massive, deep problems that STO has taken precisely 0 changes to improve.
Which is a shame, because when I was last active, pvp was occasionally really really fun. The occasions just unfortunately became increasingly ... occasional.
I'm in OPvP right now. I'm sure that if you asked, it would not be such a hard thing to find 4 other people to team up with.
I don't see the lack of segregated queues in a game with such a small population as a bad thing. Now, if we had a large community of PvPers then you could start looking into it. But if we implemented that change now, you'd just have pugmades or anyone who teams up shafted in favor of those who are unwilling to take 1 minute of their time to ask for a team invite.
I don't think you're going to GET a larger group of pvpers unless the structure of pvp changes significantly, and I think the bulk of that is pug vs. premade convincing the vast majority of players that pvp is broken or just not fun.
Thankfully, there's more endgame stuff to do, so it's not 'PvP or grind same STFs endlessly.'
Low level PvP is still fun if it pops, as queues are pretty much dead. And I think it is because the lack of P2W stuff and general concentration on your own skill, not on keybinding. The one ship from each class you can get from C-Store is not ruining the game experience.
I wonder how it will looks like when I reach VA. From what I read here, most likely I will end with "meh, frack it" and roll another toon for low level experience. And it's not about premades, was never bothered by them even in times when finding one was a bit easier cause there were still some Pandas or X-Tremes or whoever else around.
But when one reads: shields with [ResA][ResB], something fleet here, something fleet there, buy this, take that and then looks at his F2P account with EC limit, Z-Points that are 4 times as expensive as they are for the euro-zone or US guys (exchange rates, my dears) and friggin amount of P2W stuff around...
I will most likely stay on low level or take another break from STO for few months, as I have serious doubts about PvP being enjoyable for F2P player.
