So most of the time, the courier will, by high levels, be an expert at one weapon type: melee, guns etc. But what if you use all of the weapon types with low requirements? Even with skills of around 25, you can effectively use the Q35, Pew-Pew, La Longue Carabine, Ratslayer and Vance's SMG. And for most enemies, these are more than sufficient.

I'm going to try this sometime; keep all weapon skills at around 25 (maybe putting unarmed to 50 for spiked knuckles and power fist) and see how well it goes. This'll allow considerably more skill points to be put into support skills.
