...I doubt it has anything to do with BB or chainring as your ratio would spread the uneven chaintension/wear across the cog.
How does that work?
My beater/commuter has quite uneven chain tension. The frame is straight, the wheel is in the frame straight. The chainring is of good quality (it's a TA ring).
I put it down to perhaps the very cheap (£35 new) cranks and the spider being a bit off.
