Game Mechanics: group experience issue

[Treats]

If it worked this way a Level 1 could group with a Level 60.

The level 60 could kill everything and the Level 1 could just afk.

The way it is set up to work when you are grouped -- Current Level + Current Level / 2

Examples of Levels you can group with and still get experience:

10 up to 15
20 up to 30
30 up to 45
40 up to 60

If you have a player that is much higher level than the rest of your group you will need to kill more difficult mobs.
Thats just the way it works or there would be no challenge to the game.
You could rename it LeechQuest if it was coded like that.
