So i've been playing this for about a week now. i'm up to nightmare survival games and i had a few complaints/questions if anyone can address these.

Why is it that there are elemental immune mobs yet physical damage seems to run rampant?
What is the point of building a flame tower when i can build a squire crossbow tower for the same price pretty much and not be resisted?
Does physical damage get addressed in the next difficulty?

It feels bad building on an apprentice at the moment mostly because you not only have to build elemental towers but you have to build a monk aura or a smoke trap to deal with the elemental immune mobs aswell.

And yes i realize apprentice has physical damage towers aswell but they seem garbage compared to squire.
