To me it seems that the high tiered users complain about this because it was their work-around for a large exp decrease for high tiers.
I created a spreadsheet based on the following information provided by you earlier today.

- XP Points: Blue = 30 White = 50 Gold = 65 Red = 80
- XP needed per level = 1024
- XP conversion to decrease tiered XP = 75 * 50 / (36*Tier)

The spreadsheet should give some insight in how this formula affects actual leveling speed. Obviously I haven't accounted for other factors that affect leveling speed such as kill speed and the 'xp downtime' for possible deaths etc.
