Seeing that vision is important perhaps it can go to the trinket ward slot when it gets purchased with a full build. Then when you've use it, it switches back automagically to your ward/sweeper or w/e you had there before buying the control ward.
LTK KoRo41 votesYou guys realize that idea of being unable to build pinks while full-build is intended?
The longer game goes, the more safety nets are removed. Turrets damage, vision from turrets, base defenses matter less.
When everyone is full build then they shouldn't be able to dump their spare money into three pinks. It would stall late games into even bigger extremes.
TheSingularity7 votesThe biggest cause for stalling in the past was tank af compositions, an abundance of AOE dmg for waveclear and a lack of dps and tank shred to match it.
We had unlimited purchasable/placable wards and pink wards, trinkets (with their upgrades, one of which was pink), 2 jungle items with wards and sightstones all in the same season. That was season 4. Games were generally 30-40 min on average. Games shot up in duration during season 5 due to the tank meta, which involved the factors mentioned above. We didn't have the barron we have today so it was near impossible to close out a game. We actually had less vision as those 2 jungle items were removed. At the end of season 5, pre season 6. We removed the upgraded trinkets, vision ward and sight wards, reduced ward duration. And imposed a ward limit. Then due to a combination of these changes and balance problems. We entered this horrid 3 season long snowball meta. Vision did not play a role in most games, as most are at low elo where few wards are placed in the grand scheme of things.
These wards were removed for pro play. Because they slowed down pro play and reduced frequency of fights/conflicts. But guess what? NOTHING CHANGED IN PRO PLAY! If anything it slowed it down even more because they had to play even safer due a lack of vision capabilities. I miss my ward loadout of jungle item and upgraded totem. I loved lighting up my jungle like a christmas tree. Because I loved the macro game (tank jg main, so carried by enabling my team. Wards are part of that). I won games purely through the fact that I warded and the enemy jungler didn't.
Vision wasn't the problem. Balance was the problem. Because vision was utilised by few in anything below plat outside of support based on what I saw in s3/4/5. If they bought vision back to its glory. It would make the game way more enjoyable for me but would be detrimental to Riot's view of what they want pro play to be. (think there was backlash from western pro players at the time of vision reduction as well)
Neozeketho3 votesno one wants this game even shorter
BigFBear15 votesIt's intentional. Ultra lategame shall be different, with dark map. Riot want it that way. They said it several times.
QuadraBananas12 votesso many times where i was full build but couldnt get my control ward for baron ;-;
SwiftKitten888 votesthis idea is so brilliant I'm ashamed i never once thought of it.
Solicitude6 votesswitches back automagically
Read that. Still laughing! auto-magically! Good one! [slayer-pantheon-thumbs]
Cheini6 votesguys this is intentional
this is a part of the game design.. a dark map..
and is also one of the reason why Ashe is the best supp in the game ;p
Stigran5 votesAt full build you're supposed to ARAM mid and end the game :p
ZaFishbone2 votesAt full build you're supposed to ARAM mid and end the game :p
Listen to this man guys.
Bullyreaper5 votesHonestly surprised the dev team didn't think of this!
Inkling Commando3 votes
and other vision items (such as 
line) should get a second slot called "vision slot" where you have your normal trinket (Stealth Ward or Sweeping Lens) then in the "vision Slot" you can have or any ward based item. but can only have one at a time. if you go for the (or any similar item) it will be in the vision slot but be inactive until reaching the quest goal. if you go it will go there and be ready to go.
Sorostaran3 votesRito has already said that this is intended and that they like the fact that, in their words, "the map darkens" as more champions reach full builds.
Napoleon33 votesone more point to stop playing league not only the balance is aufwl right now and full of unfair champions like zed but the game just got no counterplay i stopped playing league anymore guess why? because is getting even worst since season 6 i miss old days when league was balanced and fun to play and players where not toxic or champions where not so unbalanced and items too like season 5 .
Napoleon32 votesalso the vision is a big problem right now the stealth is so aufwl and unfair i mean only good old players where bying red trinket and visions to see stealth enemys but now vayne cant be revealed and others like rengar who just being stealth for one item before they jump can be countered but vayne who q every two seconds or one if she got cd got no counterplay so fair in my opinion not even seriously and yes late game is so dumb that you cant even by visions.
Valar Morghulís1 votesCan't remember a day where League was not toxic or champions weren't unbalanced tbh...I remember the days when Rengo's ult didn't give a warning above your head...good times, good times.
CloùdCat2 votespeople don't even buy wards when they have space or gold , its not a bad idea but u think any one will late on the game xdd
Jerry SeinfeId2 votesremove wards
Müffîñ2 votescan we get a 2k upgrade on the support items where it increases the ward count by 1 and gives the wards a red/pink effect? only reason im saying 2k is so that it is unviable to rush it and is only intended as a late game buy.
Vexilus3 voteswouldn't work since most supports aren't full build by the end of a game anyway
I Am Ravi2 votesYh but i think that is the point, so if and when supports do get to late game there is an option and not just "ah, i'm now sitting on 3k gold and can't buy another item that could help my team because i need this ward slot."
Müffîñ3 votesthe amount and way it changes is just an idea. it could be more like earned 2k through support quest or cost less than 2k. its just a starting idea.
Rathar Dashing3 votesYou could just limit it by level, like Farsight Alteration. Or you could make it so that after you make say, 2k total gold from your support item, the wards become control wards. This could of course be tuned to balance it, by perhaps making it so that only the first ward placed is a control ward, or that wards placed while you already have a control ward are regular stealth wards.
Cloud2732 votesYea I agree let's remove wards completely so people can stop using them as an excuse for assassins being broken.
SpaghettiVase2 votesThey really should just replace the recall icon anyone new can learn how to recall via in game tips or the tutorial and no one clicks the recall icon to recall. People say that this will "make games longer" but I really only find this being the biggest hindrance mid game, where you have item completed while building others.
xZabaksx2 votesTaht would outbalance things
Śhunpo2 votesYou cannot purchase a Control ward with full build since that would lower the game's skill expression, and as you know, Riot would not like that one bit.
Gear5Luffy1 votesmaybe add it to the support item so it can hold like 2 max control wards
Valar Morghulís1 votesOk how about this, the first champion on each corresponding team to reach full build gets the option to buy 2 control wards maximum to replace their trinket temporarily..that way the map will still be relatively dark while still rewarding the best players by not hindering their build.
Ahris1 votesLategame is supposed to be risky. I think that is why they dont give slots for control ward.
