Some buggs

hi i dont know if i just caught a bad day but when i entered ranked matches it was kinda buggy. i was able to attack my opponent but he didnt take any damage. happened twice in a row, but on the same day tho.
another thing i noticed is when i cast a slow spell on mobs they dont realy slow down. i mean the modle is as fast as ever and thats what i see, but the actual mob is slowed down. so when i kill a mob thats already on me the loot spawns further in the back, so i guess it is slowed down by my spell just the model isnt?? dunno if thats the case for me.
