In your opinion what is the most fun class to play?
The most fun ATs to play for ME, are:
Dominator
Scrapper
Blaster
And I'm just starting to get into Brutes.
Least fun, again for ME, are:
Tanker
Controller
Mastermind
Obviously I like toons with high damage output and at least a modicum of solo survivability. YMMV
Interestingly, of the characters listed in my signature I have (avg level in parentheses):
5 Blasters (19)
2 Brutes (7)
3 Controllers (24)
2 Corruptors (18)
1 Defender (14)
2 Dominators (31)
2 Scrappers (35)
1 Tank (10)

Spectral Darque 50 Dark/Dark Scrapper
I'm going to skip the cliche answers and actually get into something serious here.
I like to be the damage dealer. This seems to be useful in all situations. Solo, there are rarely times when damage isn't enough by itself. Teamed, there's always a benifit from having 1 more damage dealer (not always true about controls/tanks... offensive boofs/deboofs yes). Also, dealing high damage means finishing missions fast... leveling fast... moving through content fast. Thing is, I actually read the stories and contact text most of the time. If I get a mission that takes 15 minutes, then the story line isn't moving fast enough... 4-5 minute missions are great.
More specifically I like melee damage over ranged. I enjoy the jumping-in-their face feel of combined combat jumping-hurdle-melee attack over the hover blast feel. (although I also hover blast in one of my primary toons). I like fast animations over slow animations. I like continously flowing movement (dual blades over broadsword... short speedy toons over large lumbering toons).
I like to tight, insanely powerful, envelope pushing builds. If a toon doesn't have the ability to make the average player say "woah... i didn't know that was possible," then I'll probably skip that combination.
I like zero-downtime, non-stop action... I don't want any set-up time... and I don't like waiting for a power to recharge.
I also have to have a name/costume/look and concept that I enjoy being.
And all my toons are monkeys. (don't ask why.. i don't have an answer).
From all that, I've come up with 1 DB/SR scrapper. 1 DM/Shield scrapper. 1 Fire/Mind blaster. And lately I've been playing an Energy/WP brute. (I know energy has slow animations, but it's growing on me.) I really don't play the DB/SR anymore becaue the DM/Shield does everything better... but before shields came along, I played the DB/SR and nothing else for about 8 months... over 6 months at level 50.
I gotta make pain. I gotta make things right. I gotta stop what's comin'. 'Least I gotta try.
