Bug on Goblin Event Regarding Mage

I hope someone finally reads what I post :/ ... and that this section even gets checked.
There's a glitch on mage that makes me take damage and go slower even though I'm not walking through any puddles, and it's evident by the wide circle I make around them. However, I still go slow. It makes me lag behind and the others are done with the boss by the time I even make it up there (if I don't die from all the damage I'm taking). This happens a little on warrior but not at all on rogue. I'm pretty sure there's something going on with my mage as it's the most dominant and happens quite frequently. Please look into this.
Not to mention the detail that this only happens on the app from app store and not through Chrome. Also, I don't seem to have ping spikes as I do on my iPad device.
