Please take off Mark summoner spell!!!!!!!!!!

I love ARAM but now because of this annoying spell i start to hate it, it's already a messay team fight mode, now there's just too much stuff going on and i cant focus/pay attention, and it's really tiring play it too, yes the spell was fun as a specil mode, but i dont like it at all when it becomes a normal part of ARAM, please consider taking it away, or at least give it a fair cooldown time like 90 sec!
