So if we are at topic about Juggler, then I want to ask a question...
Is it working with two melee weapons ?
Is it working with anything ?
If does, then does it work in AoMr ?
...It's three questions.
And yes, I think Juggler needs a huge improvement in order to make it useful.
Level first - as is, but make it work with dual melee weapons.
Level second - special reload and free swap between guns.
Level third - fire both guns at once (maybe a key to toggle fire both and fire one ?), but with, for example, 200% normal time or some to-hit minus ?
I would also ask for changing the trait text. IMHO, current one doesn't fit there.
