Ok here are a few basic choices that could work...
Melee , ala Chaos classic.
Player control for individual proxies
Switching Targeted proxies(ala ones that fall under your crosshair) from sleep to hunt , and firemines from dual to single laser.
Grabbing players , and holding them hostage...
Scratching yourself
now for an unorthadox one. Make the claw extendable(maybe a way to implement that Grav beam thing that Shadowstars been talking about , but with a big extending claw , instead of a beam of energy.) The basic premiseof this , is that AWO switches the primary and secondary from place mine , to extend/retract claw. It could have a max length of around 20 ft , and could automatically grab on when it touches a player. once they have been grabbed , you can reel em in for a quick head slice ala thos pretty melee weapons , or you can go the more brutal route , and trash them into walls by extending and retracting near one. If you get what I am saying , this could really justify the CLAW in CLAW2. Oh , to replace the pulseof energy that flies alont the beam in shadowstars version , you could have a proxy roll down/up the length of the claws "arm"
