CMON when the zeny was a problem? if its a problem for you just quit already, becouse in that case all classes should have expensive skills to for a decent damage and i really like that idea, like varetyr spear with the most sad and weak damage ever in thirdclasses skills, if it consumes a rough wind per cast but i does 6x the actual damage( the 6x its nothing compared with acid bomb or hell plant or mandragora or cart canon) could be more worthy than epic fail summon that will be 1 shoted with a trans skill like acid bomb or cs (almost all kinds of db in server can 1 shot any summon except fire one)First, you're mixing up re-use timer and aftercast delay.
Second, your info about genetics are wrong, unless you are grossly exaggerating. They have plenty of skills with re-use timer similar to sorc skills: Thorn wall, demonic fire, howl, crazy vines, spore explosion
Third, you didn't mention how expensive genetic skills are to cast, or their terrible HP mod.
Going by ymir ragial prices: (because they have less bots)
Thorn Wall - costs 300k zeny per use
Thorn Trap - costs 300k zeny per use
Mandragora Howl - costs 200k per use
Hell Plant - costs 30k per use (or considerably cheaper if self-crafted)
You are misrepresenting info to give a biased comparison.
AND DEAR LORD IF YOU CANT AFFORD FOR THOSE SKILLS, CART CANON ITS CHEAAAAAAAAAAAAAAAAPER AND HAVE AN INSANE FAST CAST TIME(no fixed cast time.... LOL? why? why? why? they can have all skills with no fixed cast times?) and know we are getting a good change with mandragora howling
