More fun build?

[Koibra]

Just got up to Core City on my SMG build on normal/Classic. The gameplay loop of it is really repetitive, and im getting slightly bored - walk up to something, burst, walk up to the next thing, burst it, etc. etc. What's a build that has lots of options and different things to do in combat, yet is still good?

Crossbow - Different bolts, lot of positioning, traps.

Chemical pistols - Well warcrimes .. fun

Dexterity based light melee focus with Versatility feat. You can engage in close combat, use stealth and traps, throw grenades, and use light firearms like a chem pistol against heavy armor and robots with poor evasion. Versatile and fun. You can have good Con if you want too, to not be a puny glass cannon.
