I'm still very against the difficult characters vs easy characters. New fighters are pulling away from that and creating different directions for characters, yes...but the new philosophy on fighters is aimed towards when to use the move...not how to do the move. This also make balance better.
Lets take soul calibur...performing 90% of the moves at a needed time is easy. Skill comes in covering the last 10% and then timing. This makes it so a beginner can dive right in and feel competent, while it gives the experts room to perfect.
Now SF4...Pulling Ryu or Ken style roll moves is VERY easy at a needed time...especially for stick players. Charge characters are pretty easy to with the buffering...but other characters are pretty exclusive to hardcore it feels. Mastering Zangiefs throws, much less his ultra, are going to take a lot more effort.
Now intricate is different than difficult to control. Ivy for the most part isn't really hard. Her moves are as simple as anyone elses and really it just comes down to memorizing stance shifts and pressing them during a move. Besides her 2 very hard to do throws she just takes getting used to. While I can easily argue that the 2 throws are a bit unfair when it comes to inputs...they aren't necessary to her overall strategy...however with Zangief, he relies on those throws and he relies on them coming out when you need them. I feel a good example of intricate is Gen. His moves are very easy, but require good timing, execution, and coherent stance shifting.
SF2HD was a better for what it was. Now I like SF4, but in terms of controls and audio it's below SF2HD.
And...beating Seth is becoming a lot easier since i found his weaknesses.
