I gust played janna and at a certain point i realized all my items were giving cooldown when i had more than enough cooldown. in the end i went with zekes, athenes,and eye of watchers for cooldown but where would you go form there? i was going to build a dead man plate just to be faster but my team won so i did not get ti finish it. should i just not worry about over caping my cdr and passives or am i missing something?
MisterHealYoGirl1 votesHonestly, enough core support items give CDR that you're almost certain to cap out at some point, no matter WHO you're playing. I wouldn't worry terribly about it; don't buy items FOR the CDR, but if they give a useful passive or active (Herald, Censer, Athene's, Mikael's, Eye), you should get them.
CDR tends to make up a fairly small amount of the gold value of items, especially for supports. The raw gold value of 40% CDR on its own is only 1200, only about 15% of what a Janna earns in the average game (and she's among the lowest earning supports; for Brand and Zyra, it's only 10%). The cleanse on Mikael's is definitely worth the 300 gold inefficiency you'd get by having 40% already.
Mysticman891 votesI've been in various debates with high elo Janna players on either side of the debate on how to best build her, but unlike many supports, building AP is actually useful to her utility (in contrast to just making her hit harder), since it increases the size of her shields (and the AD it gives), gives her more movespeed/slow via her w, and more heals via her ult.
Given the fact it is debated and top Janna players do either, one can conclude that building straight utility stuff (probably overcapping cdr in the process) is not unviable. That said, building AP is also viable, so grabbing some AP items another option. (Some even stand by going pure AP [other than sightstone], so that could be an option too.)
Personally as a (currently plat) Janna main, my preferred build is 
, sometimes swapping out zekes for 
or 
depending on the needs of the team and/or my faith in the adc. If the situation calls for both zekes and an aegis item, then I'll replace morellos, and probably give strong consideration to swapping out mobi boots for 
. If the situation is such that I don't really want to build zekes (unimpressive adc) or an aegis item (enemy team lacks impactful magic damage), I'll grab 
6th instead.
Ludens is much more attractive to me for the movespeed than deadmans might be, as I feel like if you're getting hit as janna, then somethings gone wrong in the first place, and so the armour/hp on deadmans is wasted. Ludens gives you a decent chunk of movespeed thats 'always on', plus a bunch of AP that's useful for above mentioned reasons, plus the echo passive which while not super impactful, isn't negligible either.
