As I've expressed before, my concern isn't arguing which Mega Man neutral B is better; Metal Blades is most optimal, Shadow Blades has less options but still has its own niche, Hyper Bomb seems to be least optimal and is generally unproven at the moment.
My concern is over-centralizing of Metal Blades for Mega Man's slots. By all means, dedicate 5 or even 6 slots to Metal Blade sets, now that we have the room. But don't try and tell me his other neutrals don't deserve the space or that we really need 8-10 spaces for 1xxx. This is clearly not a case of a clear-cut superior option. Shadow Blades definitely deserves a spot. Heck, it needs at least two spots due to MM's other specials also having their own niches. Hyper Bomb's a bit suspect, but we still have a couple more weeks to give it consideration.
(We) Gotta try and find some system of prioritizing for Mega Man so that we can finalize something. The following is how I would do things personally:
N - Metal Blade(1) , Shadow Blade(3)
S - Danger Wrap(3) , Crash Bomb(1)
U - Tornado Hold(2)/Beat(3), Rush Coil(1)
D - Leaf Shield(1)/Plant Barrier(3) , Skull Barrier(2)
Out - Hyper Bomb(N2), Ice Slasher(S2)
On another character this would look so much more clear-cut.
As I see it, at this point the two "outs" should be least considered, though not totally off the table. After that it gets tricky. N1 and S3 are the sure-fire moves to prioritize. Up and Down Special on the other hand have lots of good argument. U2 is experimentative but is definitely proving worthwhile to consider, but it's not necessarily the top choice. U3 is also unfamiliar but has shown to have clear benefits over U1, the latter being most familiar and still with its benefits. Finally, D1 and D3 are mostly preference while D2 has its niche as a reflector.
So I suppose the Mega Man group needs to figure out if we're going to go for more offense or more defense with his Up and Down specials, and how to deal with the preference issues of the barriers. As far as I'm concerned, I enjoy Plant Barrier, but enough experience has made me accepting of Leaf Shield so that I don't mind if it gets prioritized over the other. But like Shadow Blade, Skull Barrier should definitely not be ignored (and it won't at this point). For recovery, I think the argument is "Beat or Rush Coil", 'cause Tornado Hold really ought to stay. It's not a bad recovery by any means, and the offensive applications is well worth consideration.
If I had to ultimately break the list down further, I'd personally do this:
N - Metal Blade(1) , Shadow Blade(3)
S - Danger Wrap(3) , Crash Bomb(1)
U - Tornado Hold(2), Beat(3)
D - Leaf Shield(1), Skull Barrier(2)
Out - Hyper Bomb(N2), Ice Slasher(S2), Rush Coil(U1), Plant Barrier (D1)
From there I'd prioritize the top moves for the first 5 slots:
1321 - All 4 first-priority picks
132[2] - opt for D2
13[3]1 - opt for U3
1[1]21 - opt for S1
13[1][3] - prioritize top two moves
Slot six favors the most controversial "out" move, which is Rush Coil
13[1]1
Slots 7 and 8 is for the second neutral, Shadow Blade
[3]321
[3]33[2] - Opts for D2
Slot 9 is for a set that could replace one of the sets in 7-8. This ends up favoring preference (even moreso).
[3][1]2[2] - Shadow Blade set that opts for Crash Bombs and Skull Barrier
Slot 10 is a give away ultimately. It still could replace a set in 7-8, but most likely not.
[2]321 - Just a set with Hyper Bomb in it.
The list and system I provided is by NO MEANS a suggestion I'm pushing.
Sooo, yeah... Definitely inelegant. I tend not to do elegant on the fly. I just want to bring some sort of stability to the process, because some characters like Mega Man really do have it tough having many moves that change his style and don't just clearly buff or nerf him. But by all means come up with something better (system and/or list), or just stick to the current method of discussing. It's just that with Mega Man in particular, a good deal of discussion has occurred. It's just the amount of options that's making any finalization difficult.
