Any hyper that buffs up your speed means your ability to open up the opponent just got better and faster speed means different/better combos. PLEASE DO NOT TRY TO DEFEND THIS!
That's not what I'm talking about. What I mean is that Wolverine can do Berserker Slash -> Berserker Charge. Without Berserker Charge, Berserker Slash could just be canceled into Berserker Barrage X for mediocre damage. In a sense, the damage you get from Berserker Charge IS the hyper's damage, and it wouldn't make much sense if you could gain meter from it as well.
Firebrand doesn't have any sort of use for Luminous Body similar to that, it's just a general speed boost, so it's more acceptable for him to build meter.
Hypers that allow you to keep building meter but do not persist on tag-out:
Astral Vision, Kitty's Helper, Silent Kill, Healing Field, Chaos Dimension
Hypers that persist on tag-out but prevent meter building while active:
Devil Trigger, Vale of Mist, Sougenmu, Rimoukon, Berserker Charge
Hypers that allow you to keep building meter and persist on tag-out:
Viewtiful God Hand, Golden Armor, Mad Beast
Looking at this list always helps me categorize the boost. It's definitely not as strong as Sougenmu or Vale of Mist. In my head, I pair each one with Dark Harmonizer, and ask myself: how ridiculous would this be if the character could be permanently self-buffed? Sougenmu and Vale of Mist would be essentially unbeatable, but I don't think that's the case for Luminous Body.
It could definitely turn out to be ridiculously OP - don't misread me, I'm aware of how startling it is to find out he builds meter. I'm just trying to comprehend Capcom's line of reasoning.
? Full screen anti-air = DP+M. Mid screen anti-air = j.H and launcher. Close range anti-air = Heartless Spire aka the best anti-air move in the game + anti-air Hell Fire. Only space that he doesn't cover well enough is the area right behind/above him where some teleports occur. That's an area that Trish's Peakaboo assist covers very well in my experience playing as Chris/Deadpool.
When I say "strong" anti-air, I mean one that covers the superjump range. Ghost Rider looks like he's going to have problems against characters that can stay in the air and be pains in the ass, like Trish.
Only among a very few select people paying close attention. It's like how SRK is always salty over Zero despite him not really winning any tournaments. Maybe Firebrand ends up that way... good on paper but tough to win tourneys with him.
It'll be interesting to see if people go right to easymode characters on release or try to up their game since we're starting fresh yet also have a strong fundamental. I remember in that first month of release, we saw so many crazy teams; I'm hoping we'll at least have a month of that post-release for interesting stream watching.
I'm still 100% set on Firebrand/Dormammu/Morrigan. Permanent Luminous Body is going to be hilarious fun. Also I'm becoming much more certain that Chaotic Flame -> Luminous Body will lead to a full combo. I mean a blank Chaotic Flame, not one after a long combo.
Something like this seems possible to me:
Chaotic Flame -> Luminous Body, Bon Voyage, combo
Bon Voyage is full-screen with Luminous Body up, and Chaotic Flame causes a soft knockdown if it's done without any hitstun decay from a combo.
