Right now I play a Sniper. The hit % of Snipe is usually in the 80-95% range. It is cool. I aim to hit, but always have a backup plan for misses. No reloads. Plan where to retreat for the next shots, where to place strategic bear traps before combat. Open vents to have alternate escape routes. Have a taser or quick tinkered trap ready for emergencies. Use sound to lure enemies out into advantageous environment. Etc etc...
I think this is fun, personal opinion. I totally respect other views. The element of risk adds something good. 100% hit chance for a sniper rifle would mean you could always know you delete one enemy of choice, no risk. It would be nice, but knowing you miss 1/20 times means you got to have a plan, a way out. Good times.
