How Combo Ability post Big Bang works?

Today training my aran I notice that the combo ability buff has changed but I quite don't get how it works now, here is how it looks at max level:
Level 10: Attack: +2, Weapon ATT: +10, Magic ATT: +10, Max Stacks: 10
How are "Attack" and "Weapon ATT" different?
Also does that mean I get at least 100 attack from 100 combo counts? Or is the "Weapon ATT" passive while the "Attack" the one that one gets per 10 combo counts?

If this was answered before please link me to it.

It's worded wrong. Should be
"Attack: +2, Weapon DEF: +10, Magic DEF: +10, Max Stacks: 10"

Oh, thank you.
I didn't even bother to check in the stat window, but still isn't +20 attack a bit too much? Or did they made it so you need that to hit as much as the other warriors?

+20 Weapon Attack isn't really much considering Arans use up their combo counter for Drain, Combo Smash, Combo Fenrir, etc.

And it's no you use at pap, until u get decent level of freeze stand.
