None, MMO's I played in the past became boring very quickly, although I did spend around 3 years in WoW before it became a snooze-fest to me.
ED has a much older player base than many other MMO's, and is not a 'true' MMO, rather a single-player game with multiplayer being optional. (take a close look at instancing, how the BGS works and the actual size of the 'game world'), despite its amazing flight model, it wasn't developed as a PvP action game - which hacks off those who perceive it as such - and PvP combat, as a profession, doesn't exist, doesn't pay (although recently Arx can be earned
) and isn't particularly well supported.
If you want PvP, hang around Deciat - or SD - plenty to be found there
Sadly very little actually happens in Conflict Zones (that evil BGS manipulation again) as it is more effective to clear a heap of Low CZ's, not in open, than it is to play in Med or High in open...
As for how dedicated to the game format FDev are... They keep reiterating it is a shared galaxy among 3 modes, regularly, I think they are a little stuck in their ways there.
ETA: To reiterate - you bought a game that clearly defines 3 modes - now are unhappy that 3 modes exist - I wasn't inferring you dislike the game, just didn't research well enough the implication of a shared galaxy before parting with your cash
