I think its much better if they set a good EXP rate for level 1 til 50 so that it will motivate new players to play coz imagine how long it will take for a newbie (as in new player, a complete stranger to the game) trying to reach 50 and how difficult for a beginner to complete the job quest. Its not bad adjusting the EXP rate in that level range or maybe some quests on each level that gives an EXP reward like in Trinity, well not completely like Trinity, but like giving the character some 30-40%% EXP reward.
