you cannot buy double nomicon. because the passive is unique. its intended to be the only 20% cdr item because they gave the other items cdr. Lich Bane, Zhonyas, Banshees(formerly abyssal), Protobelt, etc.
Nashor's has 20% cdr as well, but it costs so much I highly advise against it lol. there are plenty of options though. every mage should not be hitting the cdr cap. brand for example builds rylais/liandrys. and if he WANTS cdr he can priortize it but his cooldowns are all relatively low already.
other mages with long cooldowns like lux however need the cdr somewhere in their kit so they get nomicon first or second.
And yet marksman can achieve the same with two items?
Why should a mage who doesnt like the tanky defensive AP items have to suffer?
No, cooldown reduction is something that every burst mage who isnt an assassin needs to function properly. Otherwise they do a rotation, flit about for five seconds, and if the team fight is still going they do another rotation.
Mages who arent assassins will also feel the sting of mana costs, that 40% CDR will burn them out quite quickly.
