"So your point is that Demitri having a command grab doesn't really make it different from Ryu? Ok, I'll agree with you here."
No, my point is that Victor having a command grab doesn't make him the same as Zangief. That's what started the command grab tangent, remember?
"Ok, I don't know how to discuss with you anymore; Ken IS about his fireball, just like Morrigan. Of course people would kill to have more tools at their disposal like teleports, air fireballs, dash, whatevs, but doesn't change the fact that Morrigan is just using her cool toys to jump over Demitri's fireball and doing a combo, and when Demitri wants to get some breathing space, he just shoryukens. Come on, the fireball was used exactly as Ryu would use it, and her air fireball was used exactly as akuma would use it ( I guess that no one in SF really has Demitri's horizontal air fireball, unless you go to the marvel games, but still, it is not a deep change from the Ryu stereotype )."
Ken has a weaker fireball game than Ryu and has a few more close options and combos (in general, over the course of all the SF series). And no, Morrigan isn't about her fireball, and she's not just using her "toys" to jump over Demitri's fireballs, she's also using it (a lot more than they're using her fireball in those vids) to mixup the opponent, since her air dash attacks are overheads. I'm not sure you've even watched the vids you linked, let alone played Darkstalkers for more than 10 minutes.
