You want to improve supports? oh really?
how about you just revert them to season2 where support used to be the most played role? (according to a poll i made on the french board in 2012 that i can't find because riot removed the old forum thread research)
Let's be honnest, ward system used to suck, because you couldn't do decision on where to ward if you had 15 wards or more. How about instead of giving everyone free wards and breaking the system, just increase the duration of wards to 5 min and cap the number of wards depending on how the game is? 10 min in the game---->2 wards allowed per persons (GREEN WARDS DAMN IT) 30 min in the game----->5 wards allowed per persons? (or 4)
and how about you revert all those support items that should never had existed?"but supports need them to get item"
suppports should never get items ,that should be in the definition of the role
they should be champions that don't scale that much in the game, and have an overpowered kit in early game without items ie: old

annie/vel'koz/zyra/mf, all those champs shouldn't be a support
"but how is this going to make people playing supports?"
well i don't know about you, but i enjoyed 1v1ing an adc at lvl 2 with Sona, at least i felt impactful.
