Relevant vision vs vision.

Vision is good, but there's no reason to be warding the enemies base wall before 3 minutes. There isn't a reason to ward the back of baron pit before baron spawns (unless you're chasing somebody or expecting a gank over said wall). If the ENTIRE enemy team is shoving bot lane, top lane brush probably isn't the best place to ward.

You might be asking, "What the f*** is relevant vision?"

Let me tell you. Relevant vision is vision of the map that is relevant. For those of you confused about what relevant means, here is this link. http://lmgtfy.com/?q=relevant

It means that you have good, useful vision that allows you to play safely and have maximized knowledge of what the enemy team is doing. It still won't stop you from missing minor skillshots, but it would be very helpful for ashe, cait, draven, jinx, ziggs, ezreal, and maybe even a karthus (HEY LOOK THEY JUST DID A JUNGLE CAMP AND HAVE 50 HP LEFT, TIME TO PRESS R)

Want to get good at the game? Learn to ward effectively. Dragon is always good to ward, river brush, major buffs, entrances to jungle that are close to lane AND river during the early/mid game, deeper wards mid/late game IF you are winning, ward your own jungle if you're losing. If an enemy fiddlesticks is able to ult without being seen, then you don't have relevant vision.
