I haven't played a melee class since mid-Wrath of the Lich King. I recently picked up warrior and noticed that I actually lose track of my character and what I'm attacking, especially in 25-Man raids. The trash leading to Imperial Vizier Zor'lok has to be the worst.
When I'm in a 5-man dungeon, it isn't bad; there's rarely any trash pack over five hostiles unless the tank pulls more than a single pack of trash. Even then, I can manage. As a hunter, I never had to worry too much, being in the back of everything very often. I never had to group up on a boss enough for it to be a problem. I mention this because I also often lose sight of the target that I'm attacking. While I was in the Heart of Fear, my action bars were constantly turning red because my current target was out of range and I'd have to spend what seemed like forever trying to find that same target, unless I used tab or actually managed to find my mouse cursor to click on something.
Because of my ridiculous work schedule, I haven't been able to join any 10-Man raids or any raid outside of LFR.
Has anyone had this problem while going from long-time ranged roll to a melee roll? Is it just something you have to adapt to? Or maybe it's because I'm just not doing it right and should probably go back to playing ranged.
