you can pretty much do a lot of things with a bower, but with wizzard, some things (most things) are a pain in the ass, soloing, pvp, jobbing (not at cap)
ofc you cant job with a bower without being capped, but ye, i find it to be more fun
P.S. dont go wizard after seeing some 6X wizard 1 hitting you in pvp, its normal until like 8-9D
