I'm fairly new to Dungeon Defenders and have realised that having a mix of characters is pretty useful (somewhat unsurprisingly). So, when I'm playing solo I have got in to the habit of switching between the Squire (for building spike walls), Apprentice (for building towers) and Huntress (for the combat).
Given that I'm flitting between these three characters, and am favouring the Huntress most in the combat phase, how is experience doled out between them?
