Why the current system of warding needs to change (@RiotRep? :))
With the removal of stealth wards, and the "promotion" of trinkets, Riot effectively made the map darker.
Yes I know everyone gets "more" "free" wards, but the without a sightstone-esque item it's extremely hard to keep wards on the map. The only way to do so effectively is with pink wards, but we all know their drawbacks.
That's why the blue trinket is so fudging good right now. It can allow, if played smartly, to provide a similar level of vision as a season or two ago. This is my personal experience playing since the update. Plus once you get a full build you can no longer buy a pink ward which limits you further.
If Riot wanted to give more tools to teams for closing out games (minion splitpushing), then why did you remove the ability to dominate vision across the map? That was the most effective way to snowball and end a match. The wards that are placed down are easier than ever to sweep and get rid of in their limited numbers, which I've found for the first time ever since the preseason update, the map has been mostly dark for most of the game in most every game I've played.
Without stealth wards, you are forced to wait on cooldowns to fill in your ward gaps. If they get your ward early, there's nothing you can do but sit in the dark.
My question Riot, was this planned? Because this has definitely been something me and my friends have been noticing lately.
"Dude they caught you so out, why no ward?"
"I had no way to ward, trinket on cooldown and they killed it 10 seconds afterwards Q.Q"
