no more increased exp?
Yes and no. If playing solo, you will notice less of a difference due to the fact that when solo, mobs all tend to spawn around your level. However, when you're in a group (of at least 2), this is not the case, and most monsters will spawn under your level, netting less overall experience. Falling through a trapdoor will raise the overall monster level, thus giving better experience.
