How To Get An S As Support (Very Easy)
So like may supports i've had very good games but I only get an A- or an A but i've found a trick to bump that A to an S every time
Step 1: Buy Sightstone
Step 2: When you kill both laners or when it's safe for you to back, go back to base
Step 3: Spam the wards, they'll instantly refill for more spammage
Why does this work? A big part of grading depends on wards placed and spamming wards for a good 10-15 seconds every back will significantly increase your wards placed which for a support is like getting a few extra kills in terms of grading
Hope I helped!
