Warding as a Support
So. I'm just a low-tier silver support main, but I've had some frustrating experiences with supports on the rare occasion of playing ADC that I'd like to say something about. I understand that in normal's some people play for fun and try out-of-meta things, but for those like myself who like to improve their gameplay having a support who plays like a mid lane carry can be an issue. If you don't buy Sightstone and instead ask team to upgrade trinkets or buy individual wards, that's your choice (Sightstone is more cost-efficient but in some cases you need an extra item slot for more utility, ap scaling, etc.) but building Ludens, Rabadons, Mejai's, and taking all the cs and intentionally ks'ing isn't the way to go. Building large amounts of ap for heal/shield strength and some extra damage is completely viable but simply spending 250 gold on an upgraded trinket and getting some gold income items you can get to the same point as you would with the other path but without making your team flame hate and report you and without hurting your ADC's dmg output. In summary, supports, please don't start Doran's ring and then rush Mejai's into Rabadons and Ludens, take all the cs, never ward and ks. Sometimes doing this makes you scale better and get your items faster as well.
early and hold onto it. Little thing can pay for itself and more in time..
