Yeah, I guess you could go like rainbow Lambda Cless Digger or something while you're getting better equipment. Should be OK.
Are you using Wand Lovers? It keeps Wand Gear maxed out for its duration and is a on/off skill, so using it means Wand Gear is always maxed. It also gives you a hefy damage bonus and changes the dodge action from Mirage Escape to Step. Definitely the highest priority skill to grab, I would say.
