it should be used with a shield alright,
just not a bigass huscarl or steel shield. A kite, heater or buckler are just fine though
but yea, it can get annoying, i even have a rondel&shield agi alt, but i hate players like FapFap,
who pump points into nothing but agi, then run around the battlefield, with a unbreaking steel shield, a hammer or pickaxe (or club, whichever one he uses) while riding a heavy horse, its fucking cheap and annoying,
