Reputation seems to be reduced here for lower lvl quests ("gray") to 1/5 of original value. For example for completing quest with reward of 250 you'll get only 50, so nobody will be able to return to start locations and farm rep later. Ofc it shouldn't be like that. Reputation should be reduced only for killing lower lvl mobs to 80% of original value, so by 20% not to 20%. For example for killing lower lvl mob which grants 15 you would receive 12.
Reputation for completing quests should never change. That's not exp which scales with lvl.
If it won't be changed we can forget lower repair costs from some factions, some of mounts from different races or reputation with furbolgs, cause they are lower lvl too if farmed on 60. I hope somebody from administration can respond what they plan to do with this.
