Call it a personality disorder if you like, but for me, in real life, I was never a very nice person. I've changed my ways since 2008, but I've seen and done enough evil to last me a lifetime. Pretending to cross those lines for badges was almost too close for comfort for me.
I have to give the CoH dev team credit. Aside from the silly spider bit with "Arachnos" and all that, redside was never red for me, but very, very dark and creepy. The music was perfect for it. The snake/lizard things, pretty much all of the non-humanoid NPCs were creepy to me. In short, it just wasn't fun there for me.
As for the ATs - I certainly think, after playing several tanks and scrappers to incarnate levels, (50+3), that the brutes were vastly superior to both.
The dominator - well, I was trying to get the hang of mine, called Osmosis, an electric/electric dominator - but I was probably playing her too much like a controller and not enough like a dominator - whatever that playstyle would be. For me, there were attacks that were awesome, but even with domination, the damage was too little, too slow. I never took the chance to play different powersets with it, probably because I wasn't having that much fun with the first run through with electric.
I got the beast mastery MM - he was undefeated at level 19, I think. Just never finished playing him because of the shut down, and because I enjoyed the incarnate content more than the lower level stuff. The MM is certainly worthy of note. With an intelligent player who knows about keybindings and such, I suspect the MM can be an incredible amount of fun and a lot of power. But, I can't fully express an intelligent opinion with only a level 19 under my belt.
As for the Fortunata and the crab/spider thingy - I hadn't been able to figure out a proper origin for either of those to consider trying them.
The Corruptor - a very interesting AT. If one of those had been around when I first started playing, a blaster with buffs - that's a nice combo. Stronger than a defender, weaker than a blaster as far as damage goes, but with enough buff potential to sort of even the odds. For a player like me, a Corruptor is a much better choice than a defender, and for sub-level 35, a better choice than a blaster. After level 35, though, a blaster can have sufficient defense to not really need those heals and buffs as much. Obviously, different players will have differing opinions and experiences. For me though, a blaster is better.
When the game returns, if we don't have to start from square one, I'll be playing the dominator and the corruptor and MM primarily because of my limited experience with them and want to learn more about them.
But, if we're back at square one, it'll be the blaster or brute for me, or maybe a controller.
