Sol Invictus needs another fragment slot (healing after leaving the sunspot isn't strong enough either in pve, would be nice if the sunspots tracked to you) Offensive Bulwark needs another fragment slot (seriously cmon man) Into the fray *either* needs punches to cause unravel while having woven mail or another fragment slot (maybe a fragment that extends woven mail with abilities like solar???) Cryoclasm needs another fragment slot, everything but knockout on arc titan needs an extra fragment slot (yes even touch of thunder, arc NEEDS survivability so this is the least needed to make arc better) This comes from an avid warlock player finally going into titan and finding their harsh weaknesses that I can barely cover with exotic weapons Can exotic armors help close the gap here? Yes Should I NEED them to? No, not at all
