Makoto all the way. Seriously the one major reason I got BB was when my friend sent me a vid of her astral heat. Thinking about subbing Tager just to troll some scrubs.
Lambda all day every day. Easy to learn, hard to master charecter(corner loop).
I use Bang in CT. CS still isn’t out in Europe >:(
In CS I’ll probably still use Bang but Makoto looks fun so I may use her as well.
In CT I used Ragna. I was never any good in CT, but Ragna was simple enough that I could get some decent damage off of a BnB.
In CS I use Ragna, Jin, and Hakumen. I like using Ragna 'cause he does really good damage (around 3-5k) off of regular BnB. He’s got really good range on most of his moves, ID is a good wakeup if used correctly, and I just find him a lot of fun. I use Jin because he’s got a decent oki, he’s fast enough for me, and does decent damage in the corner. He’s a very well balanced character imo. As for Hakumen…dat damage. D:
I’m also in the process of learning Lambda.
I used Jin in CT and i main Jin, Tsubaki, and Mu in CS…
Tager/Tsubaki
Impatiently waiting for Platinum.
Noel all the way.
Sometimes Tager, Hazama, Mu-12, Makoto and Valkenhayn.
Now I got to wait for Platinum (<-Waits so Impatiently)
JIN IT TO WIN IT i use jin cause…i like his style?
i main carl
:c i feel so lonely lol
plat is the most sugoi main and wow these forums are dead
In Calamity Trigger, I was a devout Bang player, with bits and pieces of Ragna in there for good measure. Once CS hit I just decided to stick to Ragna, he’s a simple character with a pretty reasonable metagame. After the long awaited Valkenhayn DLC, I toyed around with him, really really liked his gameplay and meta as well, and took him up as a second, although the guys I play friendlies with always say “Why don’t you just play your main, you know, Valkenhayn?” lol.
Tager because he can do stuff like this.

Bang 
CT: Hakumen and Jin
CS:Makoto and Hazama. Still messing around with Jin and Hakumen though. Also waiting for Platinum 
I started with Tao, then picked up Hazama cuz I like his style. Then i tried Jin. Then Tsubaki. I still play all of them, but I really only know any combos with my new favorite, Lambda. So I’m a scrub with the first four, and a scrub+ with Lambda.
Go, Lambda, go.
(Add me if you want to scrub out sometime.)
I play Tager and stuck with him the entire way. Mainly because he is the only character in the game I managed to get a decent handle on. I suck with all the other character including the easy characters like Ragna.
Noel for me, always have and always will. I also picked up Makoto as soon as she came out for DLC, but I didn’t get to really learn her until near the end of CS1.
As for ease of character use, you can go Ragna, Jin, or Noel. But I’d just suggest picking a character you like and sticking with them. Everyone is different enough to where if you put the time into learning them, you won’t have to worry about the ease of use for the BB system.
Arakune, Hazama, Ragna, Rachel, Jin, Tager.
Litchi because I like long combos, and I like to give myself a challenge by using some of the harder characters.
Hakumen is the best. I am in the process of relearning some of his stuff due to not playing much over the last two months and new the new CSII patch.
