to disable zoom on crits, it's the 2nd one from the top, top one's shadows.
Seria is just a easy server for kids(since there's no adult server which i hate
), everything is just abit easyer...like quests, i think the drops are just a lil bit lower then the normal servers. but the exp is low on seria...
and for upgrading i dont think u can fail...just that u need shit loads of money...
