I just dusted off my Sin last night after almost a year afk. Still sporting old pvp gear, but decided to quickly spec a tank hybrid spec and see how it goes in pve. Messed around in Ilum for a bit, and quite pleased. Used Ashara and my biochem heal...and easy peasy. Elites focused on meh while Sahara went to town on anything she pleases. Hardly any down time at all.
I still don't know if I should level up an alt for expansion, I am very tempted to stick the Sin and build her up and enjoy content until then. I always been a dps kind a guy fir over 10 yrs of MMOs...but the Sin tank, I have to say is somewhat fun for solo, pvp and maybe even pug flashpoints. Looks like I will cash in the free chips for PvE tank gear and see if the kiddies will scream at me for my noob tank skills
