defensively, seeker really needs evasion or some resist, they are the only dmg class that uses light armor but doesnt have evade skill. They also lack stun and mana regen(especially crit skill build seekers). So i thought something like
harad's favour: increases evasion and energy regeneration speed for certain amount of time, each enemy attack dodged/resisted gives % chance to stun enemy in the next attack(can stack to maybe 40-50% chance)
