Regarding the 6/20 Unscheduled Maintenance

if i get it right, it works as a + to the base exp. so if you have a 2x coupon and a 1.5x coupon and killed a 10k exp monster:

before:
10*2*1.5=30k exp

now:
10
+10 from 2x
+5 from 1.5x
25k exp.

the same way your mercedes link skill works pretty much.

Huh, so now it adds up instead of multiplying.. well that sucks -_-

Thanks for the explanation.
