I agree that a Druid AA build is impossible. However, I have to disagree about the class’ intended role.
Yes, Carnivory is a great AoE and it certainly doesn’t hurt to boost it as much as you can. However, Druid has quite a bit of utility outside that one skill. The attribute buffs + Hengestone allow Druid3 to support physical and magic based builds (Albeit not as well on the physical side). An INT build definitely comes together well, especially with Lycan since it takes M. ATK into account for its damage formula, but a STR build should still be viable with the right class choices.
On top of that, the high end maces provide a good amount of M. ATK anyway so it’s not like you’d be gimped if you didn’t invest in INT. Some builds, like Feral Priest, forgo INT altogether and just rely on a good mace for DPS.
Personally, I’m bored with the stationary nature of magic Clerics. I want to be able to move around and play more dynamically. Since most magic classes in the Cleric tree depend on tiles of some kind, it’s just not working for me anymore.
