Broken aggro?

Hello, I have played a Hunter as my first character on your server and had no problem with mobs, i passed them by 3-4meters in game length and they didn't attack me.
But since i created my Paladin, everywhere I go, even if i'm on the road, mobs from all sides come towards me to attack, from 10-15 meters (in game distance)
It does not seem normal, what do I do? And also when they chase me they will stop attacking only after a very long distance compared to my friend's Warrior for example
I really like your server, sorry I don't speak russian, but can someone help me please?
