Some just don't do the job completely or are just a joke. Jolder's artifact perk shouldn't even be a thing. They could have easily taken sprint lock out of the game without being lazy and waisting a slot. Felwinter's artifact is good. You gaining more a boost to stats and grenade and melee energy for a super is actually pretty good. Perun's artifact just needs to highlight enemies more clearly. Gheleon's is also fine. Adding like what nucklehead radar is pretty cool Timur's artifact needs to make the "turned" to be more aggressive and stop being idiots and standing in one place. Skorri's just needs a range buff of about a meter or 2 Silimar's is almost useless now. Thorn is already nerfed were the burn doesn't really do anything too often and I don't really so too many firebolts anymore. Over all I only see thorn, firebolts, and insinerary grenades doing damage over time abilities. Radegast's is probably the best in my opinion. Being able to reflect projectiles and gain more ammo is perfect for swords. If anyone has something different I'd like to hear it.
