oh wow, so all type of stuns are pretty useless now?

first is the effect can't be prolonged if another stun kicks in (contrast to ice and other debuffs), making everything has no effect if enemies are stunned by 100% stun of fireball, and now, no other stun are more effective than 3/4 secs cd of fireball. and worse, gale's push dan trap pull don't work after fireball stun, are these mechanics also intended?
