After playing for a few hours, my first thoughts on the balance changes seem very positive so far. Personally, it feels like almost every combo is much more tighter than what it used to be. I found myself dropping combos frequently until i adjusted my timing and even then, it still felt...off? Don't really know how to explain it. But it definitely feels like combos are tighter. Also, all the old cast's mission have been changed and are a bit different than before. Some character's missions are harder, some are actually easier (Dante's missions are still piss easy). I tried Vergil, Frank, and Nova's missions as well, and I have to tell you guys, Vergil mission 9 will make you tear your brains out. God was that an ordeal, and I gotta do it again on the PS3 ---___---
The new characters are very fun to play. I was trying out a couple of the new cast (mainly the ones I've mentioned) and they're all looking pretty solid. For now, I'll just focus mainly on Vergil though
Vergil
The first Son of Sparda is much better than i had anticipated, however, personally, I do not see him being top tier. First, I would like to say that he is very straight-forward with his game plan. His mixup game is insane with teleports along with the right assists (e.g. Dante Weasel Shot) and meter. Also, his range is absolutely orgasmic. Much like his brother, he can bully you from pretty much half-screen and laugh at you while you're going WTF O_o. His reset options are also very insane. He also has the old Wolverine Berserker Slash-->Berserker Charge BS with Rapid Slash-->Devil Trigger/Spiral Swords, but Rapid Slash is considerably slower than Berserker Slash and doesn't have any invincibility so I think it won't be as effective as most people would like to think. Also, Vergil's damage output is not very high. I had issues trying to break the 750K mark with two hypers and assists. He's also considerably unsafe beyond all hell. It doesn't help that because his game plan is so straight-forward, his moves can be easily telegraphed. Vergil is an extremely solid character, and he's definitely at least high tier, but I can't see him being top as of now.
Tell how Ammy is ok? I just watch the change log for her. I'm kind of scare to use her now.
Ammy is pretty much the same in most aspects. HHH combos are still intact, albeit much more tighter as I've mentioned already along with her hitstun nerf to her normals. Everything else feels generally the same. Glaive retains it's massive range in everything, but charges feel somewhat longer (might just be my TV lagging on me though). Whip still has its insane range. Cold Star feels a little slower as well (again, might just be my TV). The only real nerf i see with her is that she can't block during air dashes, which isn't really all too bad anyway. The speed is still there. The insane air grab range is virtually the same. You just can't derp your way in for free anymore.
