Rainbows have plenty to do in the lab. After the initial site searching that's what they're for.

Absolutely.

Also, to worry even less, the mages who did cast globals should also be "ensconced in castles with bodyguards and surrounded by other commanders and mages" - and preferably domed. Also, they should get some protection items for added security. Against seeking arrows these should be something that provides either missile deflection or luck.
By the way - yes, multiple arrows can overcome both hit points and magical wards. But every bit helps and when opponent needs 2+ arrows to kill your commander any protection doubles in efficiency, while multiple such commanders in the province become very hard to kill. It becomes cheaper just to Dispel this global.
