Making spellcasters more fun
When I make a wizard I want to be able to cast spells and defeat my enemies. I end up getting a sword and stabbing them until I hit level 8 or so and have mana production maxed out so I can finally cast decent spells and afford the mana.
Sometimes I go through most of the game without casting a spell because my sword fighting ended up scaling faster than my spell casting and it was costing me no mana to sword fight. This is despite being a warlock mage evoker.
My suggestion is to change warlock hero profession to say "level 1 spells cost no mana".
Now you can actually cast burning hands or haste every fight. It can be what you do for the easier fights.
Certainly this doesn't make burning hands any better than a fighter with a broadsword or mace.
Now you can actually play a wizard and cast many spells instead of playing a wizard and wielding a mace or sword.
