Finally, sub classes! And I also just beat the 8th Labyrinth! :A
So, for my classes and why:
Legendary Hero (Hero/Protector)
I started my team with the intention to build the Hero a bit more defensively. That still holds somewhat true in her equipment, but I haven't put any points in her defense skills in ages. I still wanted to have some Protector skills, so she was my best bet. However, I think I will mainly use passives and the elemental walls and not the Line skills.
Berserker (Pugilist/Highlander)
I mainly choose Highlander for the various passives to boost up the double to quadruple attacks my Pugilist can use with his proccs. Also the HP & Def Up are welcome, he dies way too often with having 2 weapons equipped.
Lady of Binds (Harbinger/Nightseeker)
She is debuffing and using ailments on enemies most of the time, so why not buff her with the various Nightseeker skills? That should buff her damage quite a bit once I get a few points into the various skills.
Empress (Sovereign/Farmer)
My Sovereign has no room for more skills during combat, so I wanted a class that can help in other way. Revive outside of combat? More Exp? Healing at gathering points? Yes please!
Ritualist (Arcanist/Medic)
The one thing I was lacking all the time was a proper revive that is no item. Also, I had no way to remove binds and ailments. Since my Arcanist is only there to have an active circle and then debuff the enemies attack, making him a medic was the best choice, since he has the most room to do something like this.
Being able to name your classes is the best thing though! <3
