A bit of a suggestion to make mouse controls more comfortable to everyone…
Make all attacks/spells/etc go in the direction of the mouse if in mouse mode.
Reason being, Wizard spell Earthquake and swordie normal attacks are directed in the direction the character is facing, while wizzie everything else and swordie specials track towards the cursor. This makes mouse control kinda awkward, as some moves are character bound and others are mouse bound.
EQ is one that really strikes me as really odd, btw, since Ice Pike follows the mouse instead of facing, yet is a melee cast as well.
