Leveling on this game is already easy. And adding this wont get a lot of players to more off of the bot. The bot is easier and people can be lazy with it. And there are already dungeons in place to level with. For example, CM, DT, OSI, EC, etc all are dungeons that give more exp than field mobs. There are already mutated dungeons that have stronger mobs that give more exp, MPC starts at 45. Leveling in the game is easy till 75 as long as you do quests and dailies then mutated dungeons.
- Party dungeons starting at level 20+: Check
- Exp curve for faster leveling: Check
- Dailies for easy exp: Check
- Mystic glyph runes (Wr) Exp: Check
- Trial maze for exp: Check
- Mutated dungeon with exp boost: Check
With all this is really easy to lvl. You can get to level 38+ in a day and lvl 50+ in a week easily. Yes there are issues with not as many grinding dungeon parties. But since the mission order limit is 5, most just do 5 runs and quit. Rep quest have died beause there are other ways to get exp and the population is smaller now. Mutated dungeons same idea smaller population so most just solo or duo them. Larger grinding parties of the past just aren't going to be as common now.
