I currently use 2 x 2-handed weapons. One of these is for buffs such as Momentum, Blur etc. and the other is for combat. Basically, I cast my buffs, switch to my other weapon and blow stuff up. It's great. Seems to work really well so far.

Unfortunately, I've just noticed that Momentum is still at level 1 and doesn't appear to have leveled up at all, even though I've been using it like this for several days.

Is this intended? Because the Momentum buff carries over between both weapons (or at least, they both sparkle to indicate the buff is still active).

Do I really have to have Momentum on my 'main' skill bar in order to level it up, or is there some trick to getting it to level up while it's obviously active but not currently slotted?

Thanks.
