i'm playing vanilla world of warcraft from 2005 and am running:

is it normal for a game this old to be hogging up to the minimum 50% usage? sometimes it even jumps to 80%

Are you limiting the frame rate? If not, it's possible you're just running it at 400+ FPS.

turning on vsync lowered the usage but not majorly, after turning that back off and waiting a little while however i'm now averaging 30% usage, what i'm worrying about is if a game made in 2005 can hog up 30% whats going to happen if i play a new game?

Gpu usage does not reflect your card capability of running things.
Quick example: two different stress test will both run your gpu at ~100% load however one stresses your card more than other. You can see difference in combaining your readings with temperature which will give you more real intel on how hard your gpu being stressed.
Nothing to worry about I would say
