Hybrid Melee - Alpha boosts it or no...?

So I build Hybrid Core Melee on a character who has Cardiac Alpha, and noticed that my DR buffs were exactly the rated value. I thought that was strange, as I expected Cardiac to boost the DR buffs. For giggles, I changed my Alpha to Vigor and tested whether it buffed the +Regen, and it did. So basically I'm kind of confused by the inconsistency and wondering if it's a bug. I did actually submit a bug report in game.

But does anyone know from beta info if this is expected?

Edit: Actually my regen test was flawed. I need to redo it in the morning. I think Vigor probably did not boost it. But even if it's consistent, it seems odd.

Damage buffs are not buffable. Never have been.

OK, at this point I'm fairly sure this is down to bugs.

I correctly tested Regen, and Vigor is buffing the chunk of +regen granted by Melee Core, and it's buffing the part you get per-foe. However, it's not buffing the auto/passive Regen buff we get from having Core Melee slotted (Melee Boost Very Rare).

Alpha boosts nothing for Assault Hybrid powers.

Alpha boosts the toggled-on regen, defense, and resist portions of Melee Hybrid powers, but not the passive portions, or the taunts or mez protection. It's strange the parts differ like that. But there's no way of telling which of the parts are buggy, and which are WAI.

Haven't tested Control or Support yet, but when I do, they'll be up here: http://cityofheroes.wikia.com/wiki/Hybrid

Alpha just tacks on a 7th enhancement slot.

Huh?

Right... that is definitely how Alpha works. It doesn't actually address any part of the question, though.

I haven't checked every power's info, but the passive regen boost on my Melee Partial Core Graft says "Ignores buffs and enhancements", so it seems probably intentional that that part, at least, is unaffected by Alpha powers.
