Rolplay! It makes it ten times more fun :D
There is no right or wrong way to rolplay, nor is there 'the most correct or overpowered build'. What there is is a way to have fun, which is what dnd is about!
Sure, playing as a druid with the Shepard circle is the best one for builds, as you can theoretically deal 100 damage, but rolling literally hundredes of dice is not fun.
So, play what you think will be fun!
