I quite like the idea. I haven't read everything, just a couple of pages.
Some of my ideas to throw in the pot that's already overflown
Gunslinger = Sharpshooter - I've read notions of gunslingers bieng watered down sharpshooters. This could be the case, but if the class has other pro's and contras it does not need to be I think.
I also personally have no problem with overlapping abilities, in fact I'dd like to see more of it. If the sharp and gunslinger are both good with handweapons then I have no problem with that.
I like the idea that you have the freedom to approach a problem any way you like. This is something that bugs me in some class based shooters, where the class distinctions are so pronounced you are forced to play a certain way.
The difference to me is:
* That sharpshooters tend to be more of a supportive role, they tend to be in the middleground of backline with their long range weapons.
Ofcourse players are breaking this "rule" all the time, but that's the case with any class.
* Sharpshooters tend to carry heavy gear, making them slower
If there was to be a gunslinger class, I would like it to be lightweight and fast, kind of like a beserker with guns. This would place the class inbetween the sharpshooter and support/commando. A more minimalist fighter.
* Special abilities
- Detonating grandes by shooting them - perhaps even midair, tough this might be too outlandish.
- Faster walking speed and reload? Not necesarily very powerfull: agility and reliability are more important then making heavy hits.
- Discounts are not needed I think, as the weapons tend to be cheap to begin with I think, making them even more cheap might lead to 'abuse' of this class at the start of the game.
- Instant headshot ability for very closeby clots and stalkers. Pushing the gun to the forehead, kind of brutal
* For what kind of players? The ones that like to move around freely and agile and do not mind giving up some of the firepower. Tough this class would give them the advantage of special abilities specifically for this style of play. Much like the beserker is with melee weapons.
*Pitfalls: should not overpower beserker or support.
Just wanted to say that I personally love playing with handguns, so I'm biased
