What is Cooldown Reduction best suited for?

I have always wonder what CDR is best for. Is it best to get more consistency out of your champ's kit? That's what it seems to be for, but then it seems like some champions like , , , , or don't even benefit at all with it since they either have A : More important stats to build in their kit, or B : Have passives or bonuses in their kit that lower CDs in certain scenarios.

Is it good to use it? If so then on who, or in what situations would it be best to use CDR in?

The question of CDR is an interesting one as it's always useful, it's just a matter of whether it's more useful than another item/effect you can get sooner.

Most of the time it's a matter of damage + resource vs. CDR. It's always better to have your abilities up as often as possible no matter who you're playing but if your spells do nothing then having more of them usually won't matter, or if you're oom then it doesn't matter either way.

CDR will, obviously, scale best with higher cooldown spells. And in that case it's usually a matter of who you're playing. Udyr, for example, will not use CDR as much as, say, Leona because all of his spells are low cooldown normally and you'll burn through mana really quickly if you're spamming.

Okay, I'm getting a bit too broad on this so I'll sum it up with how I determine if I need CDR: play the champion first and if you every have an instance where you keep needing an ability and can't then build more CDR than you have been. As patterns go, aggressive champion will use CDR more than defensive champions, because you're defining the tempo. There are also specific cases where a champion revolves around an aspect that's dependent on CDR. Nasus, for example, uses early CDR very well because that means more Q stacks. I always rush a kindlegem or glacial shroud ASAP on him depending on who I'm against. Supports also use CDR very well because they don't need to worry about damage.

Ones who almost avoid CDR in favor of other stats are marksmen and some assasins. Where their one-salvo burst and/or autoattacks are more important.

LOL you always rush max CDR on Nasus. With the right runes and a toplaner that doesn't hard counter him ( Darius Teemo FUCK THESE GUYS) a Nasus main can get 500 stacks by 20 minutes.

CDR is great on Nasus... -_-

Ideally, cooldown reduction is there to give your abilities more uptime. In some cases, this means that you have moderate-cooldown spells that you want to spam like crazy. In other cases, you have really long cooldowns that you don't want to be so long, and have more usefulness, especially on ability-heavy champions.

However, cooldown reduction is so easily obtainable by the champions that use it best that it is kind of pointless because you get so much free CDR from items that you already buy.

So basically I should use CDR on champs that can really make usage of their abilities and spam them without much penalty or use it on champs that can really make use of it against certain match ups. Okay thanks guys for the understanding. I always thought about the use of CDR.

CDR is generally nice if you're playing a champion that can perform extended trades like say if you're riven against a tanky top and you need to use two rotations to burst, you want your cds to come up sooner rather than later.

if you're playing an assassin it's not really as valuable though since you're meant to be able to kill people with a single rotation of skills.

In order to determine CDR you need to determine if its worth and have like 20 rune pages with exact stats for what you need for each champion you will be playing take for example Zyra

http://leagueoflegends.wikia.com/wiki/Zyra her W gives 10% CDR so you generally only need 30% your mastery gives 5% so you need 25% CDR that means like if you go CDR boots 15 % then you only need 10% in runes, or unless building something else with CDR stats.

Leona, I personally like starting with 25% CDR scaling runes on her even though sometimes it goes a little bit over what is needed because she is a support and early game if things go badly especially in lower elo it allows me to stun lock the hell out of enemies really fast.

Katarina, its a debate CDR helps every champion and can help her too however her ultimate cooldown is 45 seconds at max so if you take away 40% you get around 20.25 seconds it can be worth doing on her too in a group fight situation assuming you are able to get one kill which shaves 15 seconds off her ultimate and its a 5 second cooldown let alone two assists instant reset, although I usually go magic pen however it depends on if your team actually can time things or not really what is needed.

Teemo is a champion I say for sure needs 40% to do better spamming mushrooms.

In general there are a lot of champions but when you don't know something, or if its worth doing look up how it scales.

Viktor I hit 35% cdr without items at lvl 18, so I build the hardest hitting thing I can, and with lichbane and a 2.5 second cd Q I can kill anyone in just a few seconds. I think lazer hits 5-6 second cd so for every 2 q's you have a lazer comin your way. I melt tanks.....

Mostly I value it for reducing a champs ultimate cooldown so its always ready when battle comes around. For basic skills, I'd usually rather have more power upfront.
