I came into EX2 as a WHM cus my fc needed someone to heal and I needed a earrings for my Monk.
Let it be known I have never taken WHM into any hard content except two extremes in HW.
I pretty much brainlessly healed through it without even really trying, only time I thought about doing something specifically for healing was moving forward during the platform split to hit the people on the other side with my heals. Yeah this role is really really braindead.
