Hey,
as you've noticed, PvP in this game is mostly just gangbanging and even though the fights somewhat depend on the builds and roles of characters, they do not have as much impact as they should. The most decisive factor is obviously, luck and manpower and I don't think it satisfies most of the players. So, here's my idea.
As you gain levels, you should receive additional percents of DR, passively, though it should only affect damage from players. This value should also affect the critical hit table. This DR would be split into three kinds;
1. Damage received from Small Guns
2. Damage received from Big Guns and Explosives
3. Energy Weapons
4. Hand to Hand
( values are subject to change of course!)
ad.1
Naturally, Small Guns are tools to disable the enemy, so the critical hit table effect should be minimized, the DR would be a regular value. 1% of DR every 3 levels should be fine and a total of 10% substracted from the critical hit table at level 21.
ad.2
Big Guns and Explosives damage reduced by 1% every 2 levels, critical hit table reduced by 20% to be able to balance out with Better Criticals perk.
ad.3
Energy Guns' damage is fine as it is, in fact, it should even get a buff, since the Tesla Armor rips the whole damage output apart.
ad.4
Characters of higher level should definitely receive more damage (about 25% substraction of DR at level 21 should be fine) and perhaps receive a bonus on the critical hit chance.
All the values, details are subject to change, what counts is the general idea. Obviously, the engine does not support different damage from players, critters and NPCs, so if this thing would pass, the damage formula and engine would probably have to be reworked, correct me if I'm wrong.
