Definitely NO.
For me soloplay is a giant + but i don't want to pay monthy for "KOTOR3 with chat".
I like Trooper story, like visual style, and gameplay.
But:
1) Questing is horrible. (Tarsis 100+ quest just kills me. Thousands quest in every location, i thought that i'll love it but im 30 lvl and already sick of that. Yeah and i hate "*planetname* bonus series")
2) Labyrinth cities like Nar Shaddar and Corus freaks me out.
3) Falshpoints just suck. So hyped dialog system just don't don't seems to be interesting (Eylessys or whatever name first instance was very PRed during beta. But Hammer Station and 3rd just plain trash killing.
And what is more important flashpoints are just simply dull. No need to move, just stay on one place and push random buttons)
So PVE is dead for me.
4) PVP dunno. Never liked PVP so this part of game just cutted for me.
So in conclusion i don't see any point why should i stay after i complete Trooper and Inquisitor storylines.
Oh I've read few post above and somthing come in mind.
1) Maintenance by US clock. No thx i demand some refund
2) No reason Lag Spikes.
3) No reason dissconnects.
