So to 4-10 you will have chance to hit near 95% right and after those 4-10 hexes you will have... random hit chance based on target armor class??? like in mmorpg? no wai! But well I forgot that FOnline players used to Quakish FPS hit chance that when you aim you always hit...well excuse me that I wanna FOnline to be like mmorpg...
Oh yeah because MMOs are all about random stuff

.
Your point is to make players less godlike as they are now. Sure thats nothing good for any game when something is purely based on numbers but there again you are questioning whole FOnline mechanics and reducing skills to ridiculously low numbers will help with absolutely nothing. You will just change the environment a bit but the essence will remain untouched. SO your uber all solving suggestion will practically look like this:

So instead of mid/long range fights we would experience face to face combat that would solve absolutely nothing but actually allow powerbuilders to focus on their secondary skills since everyone will suck the same at aiming (or we will see some multi classing with minigunner that burst twice then switch to plasma rifle etc). Simply if players have more than 3/4 of their maximum combat potential already on lvl 1 then there is something wrong with it don't you think?
1 - End of insta-gib eye shots, now aiming in eyes is seriuos risk of mising for big reward!
2 - more misses, like it suppose to be in mmorpg, pvp - players live much longer
3 - players use ammunition and weapon detoration!
4 - powerbuilds are no more - they cant rape caravanas or crafter-fighter builds
5 - PS - Charisma - now is important couse its better to have more pleyers with you when go hunting with 80% or 50% as max in guns skills!
6 - Pps. Fists, knifes, spears, hammers - back in game
7 - Ppps. No insta thievery with 250% Lockpick or Pickpocktet - you can park your buggy in NCR now :>
8 As an overpowerness of bursters with this idea - Burst now for 14AP, to be burster you need 10AG, fast shot, Bonus Rate of Fire and 2x Action Boy - this will limit Lifegievers perks and in case of some builds Bonus Ranged Damage perks.
1 - Yeah like change of range from mid/long to fuckin close would rule out instakills.
2 - Only if you stand away from your enemies. Same as above, only thing that has changed is range so PvP would turn into cat-mouse hide'n'seek.
3 - Explain.
4 - Powerbuilders will not turn to harmless average builds because their combat skills are limited. + you suggest that NPC skills do not change? Only players would be limited? (good luck with killing anything without 10 man raid).
5 - Only thing that I can agree with you. Since everybody will be as good with weapon as current pope then sure you will have to bring whole gang to kill few molerats.
6 - Didn't you just said that mele/unarmed should be reduced also?
7 - So to steal one item from your cow one will have to fail 20 times and get killed few times in process too right?
8 - So why do we have other perks ingame when we can't choose any of them if we want to roll BG? Dictate how some build should look just to meet some wannabe balance requirements is even worse idea then your original one... + if one need such shitload of perks just to burst how do you want to level up such char? Using other guns until you learn how to handle BG?
You have simply ignored whole PvE part of this and even at PvP it sucks hard.
