I guarantee I was nowhere near that good. I mean, I played Ms. Fortune/Peacock, and couldn't use Ms. Fortune's head to save my soul nor combo basically at all with Peacock. I basically played Ms. Fortune because she seemed fun and Peacock for aesthetics (love how she's a throwback to classic cartoons - always used her black & white color pallet).
Yeah, they're among the most commonly played online I noticed. But unfortunately I don't find myself wanting to play either of them.
Having tried the demo for Rev 2 now, Baiken seems okay, but isn't really grabbing my interest a ton. And Answer I don't really like - he feels like a less interesting Chip (probably due to superficial ninja stuff being similar, but still), and Chip already wasn't high on my radar.
Yeah, the issue I have with quizes like that is that I often have no good answers to a lot of their questions, because how I pick characters in fighting games doesn't really track with how other people do. It's really just a matter of which one feels best when I try them out, or something particular about them catching my attention. I've played everything from rushdown (X-23, Rise Kujikawa, Rashid, Makoto [SF4]) to zoning (Dormammu, Doctor Doom, R.O.B, Lambda-11), heavyweight brutes (King Dedede, Labrys, Ares), and middle-weight all-arounders (Platinum the Trinity, Dante, Vergil, Green Lantern, Sakura). About the only consistent playstyle thing is that I don't like grapplers - which in Guilty Gear mostly just crosses Potempkin off the list.
Oh, and I can't play charge characters, I just suck at actually employing those moves in an actual fight. Which has at times caused me to not play characters that would otherwise interest me, like Mitsuru in Persona Arena, Urien in SF5 - and actually, May in Guilty Gear.
For what it's worth, my best-faith effort at taking that quiz returned the following results:
Top character: I-No
Others you tied for: Slayer, Jam
Close second: Millia
Which, well, I-No and Millia were among those that interested me a little more than the rest of the cast initially, but neither really clicked enough for me to stay with them. Slayer and Jam didn't even do that, though.
Oh, I'm sure Capcom will change up some of their characters, just for the heck of it. Spencer wouldn't be near the top of the list of characters I'd expect them to consider swapping out though. Sadly, I think near the top of that list will be Trish, who was one of my favorites in Marvel 3, and I worry that even Vergil may get the axe if they're really looking at DMC as a dead franchise at this point.
As for Dante, I'd be fine with getting his DMC4 look, but I want his moveset back as-is. Part of the fun of it is how ridiculously many moves he has - literally more than any other fighting game character in history. Besides, I like DMC3's weapons best out of the series anyway. Though if they wanted to add some DMC4 stuff to what he already has, I wouldn't complain about that.
I can't say I really play DMC for the plot - but I do have an idea of what I'd like from DMC5 in terms of setup. Just pick up literally right where DMC2 left off. Yes, that game sucked, but it ended with Dante stranded in hell and riding off into it on a motorcycle, which is absolutely ridiculous and, in my opinion, totally the perfect setup for a Devil May Cry game. Heck, it would even allow them to easily re-introduce Vergil even though he died in DMC1 - because of course someone like him would be in hell after dying.
I don't want Capcom trying to replace Dante as the main character though, so if they made it Dante's son, that I wouldn't like at all. I would like if they followed up making Trish and Lady playable in the PS4 version of DMC4 with giving them playable parts in a DMC5 though. Especially Trish, she was a blast to play in DMC4.
