well..khuutra..it's your own fault if you fall for it..they are blockable..wich makes it okay..and if you perform one and it doesn't hit..you're freaking open to huge combos..so..it's a fair trade...
it all comes down to your skill in evading and blocking..making sure you don't get hurt, but raping your opponent with your own home-made combos..wich sometimes need items you have to look for in battle..wich fuels the battle instead of becoming a boring block-attack match
