Thieving XP Rates

[thc]

Hey,

This is my first post and i'm quite new to the server so sorry if this has been mentioned before...

I've just hit 90 thieving which has taken a while, but now i've unlocked the Gem stall i'm only getting nearly half the xp that I was on the spice stall.

80 thieve required for spice stall & 5,000 XP per click.
90 thieve required for gem stall & 2,800 XP per click (and no loot either?)

it just seems a bit unbalanced and feels like the grind was not rewarding if you know what i mean?

thanks for reading.
