in respond to some of ur question 3 and 4
i am a wiz3>link1>sorc2>WL
wiz 3 is good becos u will need magic missle to deal most of the dmg, it has a decent cd for u to spam too.
not to forget quick cast for 50% magic dmg boost|so quick cast + magic missile = everything high chance is dead ,linking makes it even quicker
kinda ur main skill till u get ur bats and ur WL skills
as for sorc/linker/WL
ur link helps u deal more dmg to multi target,and wat i mention above ,
quick cast + invocation boosts the dmg of ur bats(dark element from sorc) , Dark Theurge(dark element from WL) and Pole of Agony(dark element also from WL)
so WL actually help boost all the dark element spells u have
dishing out a lot of dps,BUT this path is more for single target,
great for boss, decent for up to 5+ mobs,bad for anything above 10.
pvp wise,itās good,i wont tell u how good.
u go try it out when u get it :3
and sorc 2 would give u the ability to use summon when u dont feel like spamming spells or do the Double TS skill switching skill spam.
u wil feel really bored during ur early stage of lvling,
but once u reach sorc 2,that is where the fun begins
sorc and WL syntheses very well with each other
and personally i havet o thanks @moises_andre12 for suggesting it in the sorc mega tread.
