If you're worried about hate use pax(if you have no items at all at your disposal you must be doing something wrong), still worried get a scholar in party. It's absurd to think that the cor is the one who has to worry the most with samurai, warriors, rangers etc around, even more while using a ws that generates smaller enmity per se.
And it's not a phobia of casting magic, there's just no point to do it bar emergency, which makes mp gear redundant and stupid. And nope, I don't live in a perfect world, my ls is full of gimps and we only use whm mules, yet I absolutely have no need to play bard style and enjoy epeening to my heart's content.
