Say I make an HS mule...

How is +50% EXP from HS 110% total EXP, whereas someone leeching would give you more? That doesn't make sense. O_o

At least in gMS, another problem that's arisen with the new exp split is that a lot of exp from holy symbol is wasted due to the 110% pre-party bonus exp cap. For example, if you were training with one other person in your party at the same level and with holy symbol, you'd get a (0.2+0.4)*1.5*1.1 = 99% cut for your own kills and a 0.4*1.5*1.1 = 66% cut for your partner's kills. Now, with the new split, you should be getting (0.6 + 0.2)*1.5*1.1 = 132% for your own kills and 0.2*1.5*1.1 = 33% for your partner's kills. However, due to the 110% exp limit, the 132% for your own kills goes down to 121%, essentially wasting 11% of each monster's exp with this party setup.
