Hey @nikos32,
According to my experience assasins are getting slowed/stunned with an immensely high rate. It doesn't matter if i use magic shield skill and/or wield a scorpion shield on top of that; i'm getting stunned almost every light attack or slowed even with the slightest suspicion of ice attack happened to casted around me... In rush hours slowing/stunning skills are used in everywhere and assasins have no protection against it since the resistances doesn't work as intented. No matter how much resistance an assasin have the result is almost the same. Also, archers' ice/Lr shot skills has relatively low cooldown time and they are able to bomb around with those skills; some of them doesn't even bother themselves to use regular attack skills of them in combat.
With these slow/stun rates, especially assasins, have no use except to kill farmers all day long repeatedly. Assasins should have been able to deal good amount of damage in short time and receive high damages in return and we have that already, which is good, healthy and accepted. But the slow/stun rates enforcing this class to be casted out of main pk in rush hours where is slow/stun skill are used widely by almost every class with high success rates.
I do not imply assasin should never got slowed or stunned but the rates are high and needs to be regulated.
