That's how it works for all classes. Its the lack of gear you have measured against the decrease efficacy of state weights per level.
Might also be a lack of spells and filler, depending on what level you are.
Thank you for the reply! For a bit there I thought maybe I was just seeing things.. or maybe it was how I played the warrior.. truth be told.. it's still probably a good portion operator error on my part. *laughs* BUT!! At least I know it's not just me!
There may be noticeable jumps like a new 80 going to Catalysm areas or a new 90 going to some MoP areas, but all in the skills you picked. If you hate life now as a warrior, the skill trees used to be way more extensive (which personally I liked).
