physical resistant banker with a warrior when I could not beat the physical resistant one with the mage after trying ten times.
This is because the Fighter is simply a better class than the Wizard,
even for spellcasting. The trick is that you get a full health and mana restore whenever you level up, and the fighter needs less XP to level up than the wizard. Because he gets "free refills" more often, he actually ends up with way more mana to work with over the long run and ends up having a better spellcasting presence than the wizard. If you time your level-ups to happen mid-battle, a Fighter is positively monstrous in terms of his damage-spiking potential.
The wizard, on the other hand, is in the running for the title of "weakest class in the game". Definitely not one I'd recommend for beginners.
I don't mind using the mouse every now and then but it would be nice to use arrows for the straight paths. Looking forward to that.
The nice thing about mouse-over is that you get full combat prediction of what you're about to attack. Very helpful tool, especially when facing enemies with obscure abilities.
