I believe that if life gives you lemons, you should make lemonade... And try to find somebody whose life has given them vodka, and have a party.
first i would like to say that i think synergia should give a fixed amount on fragments when purchased, for example 1 frag for every 2m spent. its not like anyone would have any unfair advantages or disadvantages over it.
then to get back on topic, i think double XP on runes is "you wish" and will never happen. but my thought was make a "casino day" and all spins are 50% off. now that should speed up the economy and gem purchases drastically.
