hey there, new player (14 Sentinel) looking to 'main' the republic side. my IGN is Melzas

Besides rolling all the class storylines, is this a long term mmo at endgame or does it get boring after all the main story is completed?

I was subscribed before the Nico blasters were a prize for subscribing, do i have to buy more subscription or will i already qualify for the rewards?

So I Started this game like 4 days ago and it was that 12xp event thing, I started as the Smuggler/Gunslinger and I happened to get hooked onto the main storyline, avoiding everything else in the game. Nek minnut I am lvl50 with incredibly ***** gear and I have no idea how or where to get good affordable gear for my level. I REALLY need new gear because its at the point where I can only take on 2 strong mobs at a time....and that is pushing it... to be honest starting as a new player on 12xp event seems like it shot me in the foot in the long run

Sith warrior vs Knight and Consular vs inquisitor Also does it make sense to be a light sith or does it contradict the plot a little?
