It's dead Jim,
There's no dev interest (some mostly bad looking ranked rewards every 3mo to keep the few pvpers that haven't jumped ship hooked(lol &the lengths they go for said "shinies")), engine is very unfriendly, expect pvp balance to only go downhill etc
TOR is all about casual PVE & RP. This has been quite clear since SOR at least.
Heck, they're going with a MEish story only expansion "where choices have (the illusion of) meaningful consequences".
Pvp servers in TOR are just small, rather toxic communities that love generating drama.
If you're not into that, there's no reason to join/stay on such a server.
Let them die
&stop subbing, they don't deserve a PvPers $
toodles!
