I go through phases - I won't play for a month (or 5), and then play for 20+ hours one weekend when I finally have some down time. I should probably FTP with that sporadic schedule, but I don't. I'm still a subscriber.
I would definitely play more often if I had friends that also played. Right now the only other person I know that plays is my 9 year old son (he's better at it than I am), and I can't play with him because his character is using a slot on my account.
If you are on the harbinger look up Bremiaha, Nehe'a, Near'a or Liz'lora on the republic side (have other toons but those are the ones I am on most). Have imp toons tool, but can't spell their names without looking.
