Me and some friends started up a tatical play through. We have 1 person going summoner and then most likely into geomancy once the hit 10 summoning. 1 person is a water/air mage with a focus on healing and frost.

I went with a necromancer tank since my other play through was with a ranger. ATM we are struggling on fort joy. I know it's one of the harder areas. Will having a 2mage 1 physical party get better later. I am usually the only one breaking armor so anyone who is beefy is a huge pain for me and even though I am usually way closer to the enemy they often ignore me completely in favor of wasting a turn to rush after my friends who have way lower armor.

Will we have more fun/better off just going 3 man mage, or is there a way to have more enemies focus me?
