Order of Preference for Weapons:
(1) Psionic Weaponry
(2) Shields
(3) Electric Hammer
(4) Dual Blades
(5) Street Fighter
(6) Ball & Chain
(7) Energy Blade
The top two are far and away my preferences, considering we already have different forms of blades, as well as weapons similar to street fighter and ball & chain. Yes, the hammer is also similar to what's already around - but it's ELECTRIC... as a long-time Thor fan, I definitely enjoy considering the possibilities there.
As for the defensive sets:
(1) Force Field
(2) Willpower
(3) Vibration
(3a) Density Control
(4) Shields
(5) Growth
Force field would give the tech/science meleers a new theme and the magically themed possibilities are endless (one caveat - I'd rather have force fields that are not bubbles, though - fine for the defenders, but please something that's more formed to the body). Will power is great addition for those that want to travel down the "natural" path - something that's rather limited in possibilities right now. Vibration and density just sound interesting - don't know enough to give an opinion, but I like the potential. Shields as defense? Meh...nothing too exciting there in my opinion. And growth? I like the idea, I suppose, but not all the complications that would have be solved as part of it. If anything, put that one on the backburner for now, and come back to it after implementing some more choices for meleers sooner rather than later.
Just my quick 2 cents.
