Sadira scream OP to me, base on her moves.
- Double jump, which not only mitigate the risk of jump, but add massive mix up possiblities.
- Combo from throws, enough said
- Combo from an Antiair special attack flash kick. Again, executing anti air like Dragon punch in Street fighter is a calculate risk. Now, not only the risk is taken away, but can link to massive combo string.
I think, maybe she will get many nerf, & maybe get the (while effective) lazy game balance design call nerf the hit point or damage, like Capcom did with Akuma & Seth. And the oppsite to Character like Zangief, which somehow Capcom hated or something, as he doesn't get many effective moves from the ones he already have in street fighter 2 days, never mind he has been most street fighter game.
I hope to be proven wrong though, & they made the character more balance. At the moment Double Helix seems to go crazy in her moves & mixed up, maybe due to her being new, & they do not have the retriction to be faithful to the original KI casts.
