Please get rid of the late XP penalties. I dont think anyone cares if someone jumps in late and gets full xp for it and it prevents people from joining groups that have been in quests a long time. Many times Ive avoided helping someone thats been in a quest a long time because I have an xp pot going and dont want to ruin my 1st time xp bonus by taking an 80% xp hit. The longer they are in a quest the less likely someone is going to jump in and help them.
