The easiest class to play?

The one you feel most comfortable playing. Some weapons are faster and slower then others. I'm running attack speed idols with a mace and it's very smooth.

Depends on what you consider easy.

Fighter and Paladin can be easy because you have a shield so you can block more damage and use your time blocking while learning enemy attacks.
Ranger can be easy because it starts with a spear, allowing you to keep at least a bit of distance while attacking.
etc.
