thx for the flowers
i have to add that stunning is not influenced by magic attack, therefore magic defense (from runes) does not influence your magic stun resistance but magic resistance (hero capabilities) does. i also did point out and can only repeat myself that magic defense is usefull in HR and quests and most of the times not needed in PVP. therefore in my humble opinion magic defense on main heroes is usefull in lower and medium game play but has to go after you reached the endgame and needs to make space for more usefull sancts.
