Hi,
I would give copper for a though about guards.
Which one you use, how useful you find them, do u swap guards from some reason? Do u consider guards something worth thinking off or its actually filler which sometimes happens, but never worth thinking off.
The best response is from ppl who use some, and can tell if they liked it or not.
So far i played only with earthgrab on wizard and do not like it (eg, wizard is cool) since it has quite low proc rate, and i do not play in close combat that often.
