I played for 5 years, got to the point I could support my playtime with in game currency. Was a month from any factions carrier, 3 months from being able to use them well.
Seriously if you don't enjoy your first trial week ( or 3 weeks for a "buddy link" ), this free to play method still isn't for you.
I quit because of the rampant botting everywhere, from the markets, to the PvE content, and only 10 minutes a week of good PvP, with the rest mostly grind. I carebeared to the point I could go afk in the hardest missions and come back in 5-10 minutes and move to the next section.
The hook is the people you play with.
