DISCLAIMER: This thread is more to draw attention to the fact that for some of the community (obviously including myself), we feel as if we're missing out when we level with friends because it's less efficient. I am aware that there are better fixes for the issue I'm describing than increasing party XP. The existence of totems still does not make this problem okay. Recently I asked here how party XP works, and the only real credible source is the wiki, which says when someone in your party kills a mob within 20 blocks of you, you get an additional 20% XP from that mob, and the original killer still gets 100% of the normal XP. While this bonus XP is nice, as a whole it still discourages people from grinding with their friends since it's less efficient. It's almost always going to be more efficient to grind by yourself in one spot as you will be able to kill more mobs and therefore get more XP. There are very few to no places where mob spawn rates are high enough to warrant a party and still get enough XP, and even then you aren't really benefitting. I think to encourage grinding with friends there should be grind spots with very very high spawn rates (even the current grind spots with grind mobs aren't close enough to need this. Sure, it helps to grind with others in these spots but only really with totems). Another great solution would be to increase the bonus XP from 20% to 100%. This way there is no loss when someone is fighting alongside you and you can actually benefit from the extra player (and it would just be more enjoyable and sustainable) without losing efficiency. In order to help remedy allowing AFK leveling (one person kills with another nearby) you could make it so you only get XP if you got at least 1 hit on the mob, or perhaps you must attack SOMETHING every few seconds or risk not getting the bonus XP.
