Exactly how it sounds. I hate that everyone is shooting with 95% chance after level 3, so I propose the that 95% chance to hit can only ever apply to hitting the torso. Eyes/Head/Groin/Legs have a lower maximum to-hit chance. I want the chance to hit to reflect just how much damage they are capable of doing.
95% - Unaimed/Torso
85% - Arms/Legs
70% - Groin
50% - Head
40% - Eyes
To be honest, I'd quite like harsher penalties for hitting anything, not just aimed shots. Combat is boring when every shot is guaranteed to hit.
And don't argue the whole 'What if people want to be weak snipers?' angle. FOnline is not Snipers/Tanks. Most experienced characters are tanksnipers. They have beefy HP due to lifegiver, and all the crit perks.
