Logged off this morning at an unholy hour. Got to lvl 12 on a Jedi Guardian (class I'll be rolling at launch). Got to Coruscant and did the Esseles (first Republic flashpoint). Also picked up my crew skills to play round with.
On the whole, very, very impressed. The gameplay mechanics are superb. Getting my lightsaber was epic, and nothing beats pressing Z and flicking it out. Also love the mod system. Got a green blaster random drop, stripped out the Orange crystal, and stuck it in my Lightsaber. Very cool wondering round Tython with the only Orange Lightsaber!
The flashpoint was amazing. Nice mechanics for an instance tuned to just DPS, and still a challenge. I did it with Chug, with our two companions, and we really had to think for one of the fights. Really keen to see how they're tuned for later levels and the trinity.
I've already uninstalled the plethora of MMO's I've tried since leaving WoW, and it looks like WoW will get uninstalled before the weekend is out (something I've never willingly done in 6 years!).
