No one thinks edge of the night is out of control?

Abyssal and zhonyas was given cdr because they nerfed the ap because the items had too much offensive power while being defensive also but cdr also helps offensive power they could take away the cdr from those items but then you would say give them more ap which defeats the point of why they were nerfed in the first place. as i have said 7 seconds is low cooldown especially where high damage spells is concerned and 7 and 12 is without cdr for a champion that builds 40% cdr what is the actual cooldown on the spells 4 seconds and 8 seconds (give or take a few miliseconds) ? one in the realm of a spamable spell and the other on a low cooldown with arguably better cc than most supports pulling an enemy out of place a melee support is considered largely broken and unfair for the same type of ability and that ability is a 20 second cooldown spell from level 1 and goes down to 16 seconds still more than arhi's e on a champion that is more situationally useful and doesnt get to build full damage or defense while getting 40% cdr you have to build sheilds and other items with inefficent stats to get 40% cdr. though ill give it to you that arhi's e displaces you a shorter distance but its easier to hit and your whole usefulness doesnt revolve wholly around you hitting it. cass' q is a d.o.t. nuke and her e is poke without a poisioned target and a rapid fire nuke with a poisioned target that also has sustain (health and mana) properties viktors q is far more balanced than cass's kit but mages across the board have too low a cooldown problem they think nothing of hitting a target with burst every 3 seconds but complain when champions with 8-14 second spell rotations jump on them because that how long it takes for the engage to come back up none not accounting for that they have shields and or cc/ mobility in that has cooldowns a fraction of that (as you say arhi has a 7 second cooldown burst spell and a 12 second cc ) but when an assasin has to dive in minions every 8 seconds while drawing minion agro and to do their job and a bruiser has to dive in every 12 what was the cooldown on cammile's e that was constantly complained about from her release 16 seconds -9 seconds at lowest and bruisers cant take half of your hp while staying out of range like mages and marksmen do but they also have to have longer cooldown spells with less damage and utility same with tanks get their defensive items nerfed because games are too long then get their offensive items nerfed because adcs are abuseing them
