Well to be fair the best way to use Diablo is to E first , then charge them into a wall so your team can kill themcharge them towards your team so they are cut off from their own team . Artanis is very niche and doesn ' t really fit into many compositions , which is why he feels like that . He is good on Battlefield of Eternity as a second tank with the talent at level 1 that gives bonus damage to minions etc . I ' m not very experienced with him but in general his role is to harass the backline and draw their melee into duels they can ' t win . I believe his Q is not really to be used that much though this will change soon , W is to get quick procs on his shield and to do damage , and E is to set up quick kills from your team in a similar way to Diablo before .
