Have played for too long Quake Live (Tier 4) and there was mostly rockets (calculating where the buddy is gonna be, mostly...together with the ping in the specific match) or careful burst fire with other weapons.... The thing is both UT and Quake do require very different skills among its weapons. Quake Con IMO helped the professionalization of those players a lot, Battlefield play for free (maxed out all characters in several accounts, lol, till the game got closed for ever) , and there I was both a sniper (mostly very long distance, good at calculating the bullet drop and that and firing fast) and and mostly an engineer (which had good cqc guns) . Later on PlanetSide2, and there I played differently, mostly as a cloak spy, but again also as sniper, bolt fire again and long distance. In these games like that one, where aaall is based on what weapon were you able to purchase or unblock with game credits, the confrontation with another faster rpm weapon, of higher impact and less recoil, etc, is that, related to what you could get. Still, the one headshot kill of a sniper, with every sniper rifle in every fps game, allows anyone to keep an advantage even with high level armed to the teeth players despite you being new. Later playing too, but like every 2 weeks, lol, to Arma3, as I just purchased, also to be able to edit/mod for it. I have even videos in youtube of the accuracy I got with a basic pistol in BF play4free, with the M1911 pistol (BTW, too far with what that pistol could do in real life, lol...) but not sharing that here... My method with that one is, obviously non burst (but almost) neither bolt sniper fire... usually knowing am gonna miss some bullets, but rapid and accurate firing of the little magazine it has. usually the first two will miss, the following 5 or 6 will be really hitting something, lol..... Anyway, lol, is funny how badly these games do reproduce reality... Luckily, as I would really hate to be in any of those situations in RL...
Anyway, for those of us getting old... is funny but I notice a slight downgrade in reflexes in Quake Live (as no other game put that more to test, too) , and for sniping very far targets, I also realize I need the glasses now, heh.... And when someone ask me the age, every freaking little kid gets super annoyed, grunt...That's a question never to do in an fps game, for a large collection of reasons...
However, I don't know your case, but my desktop PC is super old right now... late FPS games just don't allow good performance even in low, or barely... that's another issue for playing right now... tho, (except today, lol) my main issue is available time, lol...
