Depends on the warrior spec, really. When i first leveled mine i too had problems with multiple mobs. As i got to know the abilities and started using my big slow sword things got easier, though. got to a mazimum of 6 at a time (with the special 30 minute ability, though).
been playing for 3 full years hardcore. By this i dont mean just leveling (3 characters at max level at first, now 4 with a 5th one coming), but also hardcore raiding (5-6 hours raid without counting the preparation in consumables). Now i only play casually as often as i want/can (which is less than 1 day/week).
If you want to reduce your time, you can. It does feel good to achieve things in WoW, but its nothing you cant quit if you have something better to do with your time.
