well maybe not change server exp rates but rather lower the exp required 'to next level (tnl)', giving a somewhat overall 1.5x~1.75x exp rate like feel. By having trenches of exp tnl reduced that encourages players to strive for higher levels and be rewarded with further exp tnl reduction. Also, so the old players who have previously put in the hours of grinding/ pq can reap the benefit and have their old exp gained throughout their levels, carried forward onto the new exp required table and not feel left out. Meaning if ure lvl 50 before the lowered exp tnl, after the changes, you'd be compensated the excess exp you've gained from prior levels.
For example: from an old thread. Feel free to customise rates
