In UT, the Sniper Rifle and the Minigun are Hitscan weapons. They don't actually travel from source to target. They are instantly there. (It is online latentcy that causes you to have to lead your target) The Rocket Laucher is very effective in UT, if you know how to use it.
You can load up to 6 rockets, fire them in a spread or tight formation. You can also get a "lock on" with the Rocket Launcher.
If you feel it's too slow, you can also enable "Instant Fire" where you can fire single rockets at a quicker pace, (This disables the ability to "load up" multiple rockets.)
Alt-Fire with the Rocket Launcher gives you the ability to fire grenades. The same rules apply. You can launch up to 6 grenades in either a spread or tight formation.
Please do not underestimate the weapons of UT. I believe they are the most balanced weapons in any first person shooter.
Pretender, I am sorry, but the Sniper rifle is a hitscan weapon and I've gotten MANY one shot kills with it. You aim right at their throat. HEADSHOT!!! INSTANT KILL!!!!!!
