Wyll actually can make a decent tanky character with the moderately armored feat. The problem is that eldritch blast spamming is superior to his melee capabilities. This may change on full release if they add the Pact of the Blade feature, which should let Wyll change other weapons into his pact weapon (rapier) and let him have an extra melee attack at level 5 and finally will add his charisma modifier to his melee damage as necrotic damage type at level 12. That should make him more viable as a frontline melee. He still won't outshine the damage say a paladin could put out but he would definitely be better as a frontline melee than he currently is in EA.
