I'd more say it hasn't led to it cos it hasn't been done properly, the cap is to high and other guns don't seem to be easier to cap or at least aren't as good as they should be for how much closer to get you can get.
The sort of thing I'm looking for is for example if somebody chooses a wyatt build they could easily cap it cos its a low tl gun, this means they have spare points for resists speed or other things. If people were to use say the freeman it would be hard to cap so you would need to put a lot of points into damage skills as such sacrificing other things like speed and resist but you would obviously get more power from your gun. And of course if you really want you could just have a similar setup to the wyatt guy and do similar damage as while your gun is better having less points spend in combat skills means you don't cap it.
This would make people use a variety of builds I think as it would make all guns viable, they would more be for different styles, for example the lower tech guns would generally be for people who want higher resist builds while higher tl guns are for people who are confident in their ability to avoid damage and want to hit hard. It would require a lot of work and it would be nice for a high damage build option for lower level guns but sadly I don't have a clue how you could do that while having all the rest of it.
