I've actually always thought the "easier" of the meta-character types were "Balanced" characters.
There's something about being at a serious meta-disadvantage (a rushdown character who can't get in, or a zoner who can't get them out) that takes a sort of skill that playing a character who has an answer for everything just won't teach you.
At least for Sonya, I find Special Forces (zoner) and Covert Ops (rushdown) more difficult than Demolitions (balanced) given in those if I can't get in or keep can't them out I have to deal with a whole bunch of shit.
Also, stop replying to NY-Shadow everyone.
