Warding and You
Do you like getting ganked? Do you like turning a corner and getting killed by the enemy Zed? Do you like having the enemy take Baron while you had absolutely no idea it was happening?
If you answered yes to any of these questions then by all means DO NOT BUY WARDS. Wards are meant to help you see parts of the map and would make all of the above more difficult/impossible. Even though Riot made them only 75 gold this season instead of 100 gold IT IS ALL A NOOB TRAP. Pros never buy wards, check their statistics. If you want to avoid climbing then by all means you must listen to this post. Such a simple thing can actually lead to climbing.
