i am in global server too, seldom play pvp
main jack, kai, jenny, deborah

chris very weak imo. low damage but tanky, going to be replaced sooner or later.
kai is good, but until certain level den his aoe damage is insignificant already. even my lower damage jack outdamage and outlive him.

i love carrot, glass cannon, help get ss in many cases

my pve team got deborah,kai,jenny,jack,mu,carrot,sonicboom,bard

alfred is not bad actually, just that it is hard to farm all the genes. jack is better compared to alfred imo, due to leech life.
