Well Tina is mega safe
Hayabusa is a sniper, so its difficult to comment on him in a traditional fashion. What I mean is that he has very good "get in" and can come in from range with a fast guard break and has fast transitions into his ninpo stance that can't be interrupted (at least by my character). If he is ballsy, he's got a string or two that end in guard breaks but they are somewhat reactable if you've seen them enough times. Otherwise he's kinda unsafe, but he gets in so easily, risks so little and has such high damage output that virtually who ISNT a Hayabusa player would fail to sympathize with him.
Frankly I look at Hayabusa and I swear, I almost see Viola. "Let me mix you up three times before you can do anything hurr hurr hurr". Yea for him, he can stay unsafe once he's exhausted his guard breaks/ninpo BS. He deserves it.
Hayate can choose to play safe, but he has to "charge" his attacks and thats always going to be a problem against anyone with decent reflexes at high level... which is usually everyone. He just needs more love overall....
Kokoro is safeish.
Ayane is super unsafe.
Leifang super unsafe.
Bayman super unsafe.
Zack most unsafe character ever with pretty much no redeemable qualities outside of devil jin mode.
Kasumi super unsafe.... maybe getting safer?
Hitomi.....sorta safe?
Yea I mean these characters can all still win and, in some cases, stomp the hell out of other people when they guess right. In some cases it doesn't really phase them much. But it's annoying more than anything.
With the lack of safety, I guess what I'm trying to say is that it's not as much a threat to the competitive nature of the game as it is a threat to the fun factor. I don't like having more reasons to not attack, than I do to attack. I've got enough of those with my opponent using sidestep evasion, defensive holds, crushes, sabaki's, and having him being at advantage over me.
So, once again. This isn't a mandatory change I think... but it would definitely be a nice.
