My openion!!
u hav two options i will tell you the plus points and minus one's!!
doing SQ bfore 130 is of no use i think..
coz thr are so many c3 party's n alll shit's for lvling up as fast as u can till you bcome g9..
1.sq's @ lvl 130+
it is helpful in making u g10 the fastest way..
will give u loads of lore's and xp to bcome g10
but not many char's need lores to jumble up thr skill points now and thn..
for eg. mages and archers stay g7 blood so no use having lores..till g10.
Warriors nd hk's hav nothing to do with blood they just keep putting thr skill points in int or dex to wear the respective set's!!
up above till lvl 140 u hav diffrent maps nd partys to lvl up like Tao nd T1 etc..{basically called leeching,i hate it but though its best if u wanna be a AURA}!!
2. SQ's at lvl 160..
in my personal openion its the best time to do the Sq's
bcoz at this lvl thrs no use of so called leeching thing..
u hav to do quests,and u live on tht quest xp's bcoz only tht xp can make ur xp bar move to some xtent..leeching wont do any good help's!!
so whn u do SQ's u get enuf xp helpful in making u AURA!!
Im a Mage..so this goes for archer's and mages!!
Basically mages and archers stay g7 blood till they are 160..
the moment they get aura they change up to their respective FINAL sets!
so SQ"s are helpful at this time giving xp plus the lores coz these char's need imba Lores to finalize thr skill points..
sorry for such a long post..
but i though its important to make it all clear!!
