I wouldn't mind to see BLM trade away more defence for stronger spell capabilities, I always enjoy the style of "glass cannon" while playing a mage character no matter which game.
It makes you think twice about pulling aggro, taking uneccesary damage or play smart to avoid heavy meele enemies which can cleave you in half with 1 or 2 blows.
I've always found it exciting both in PVE and PVP settings, and for me its what defines a wizard and mage type characters who usualy dress in cloth, robes or leather, offence is the best defence sorta deal x)
