-at a low level warding is not important. Warding is always important, and it gets annoying how many people overlook it. Yeah sure if your playing in 500 elo you can just pick garen / morde / mundo and pubstomp all day no need to ward LH or anything. ALWAYS practice warding UNLESS your playing the carry than you should request the tank / support wards for your team.
-countering is also not important because you dont know what the other team picks anyway. Anyone can counter jungle as long as they know what they are doing, and anyone can buy a banshees veil against Ryze, Annie (insert random caster here) Just about every champion has an item that "counters" them. (Also in ranked you can see who your opponents pick )
-Map awareness is a must and with map awareness comes communication such as calling mias and pinging the map.
This is wrong, I've noticed the better someones map awareness the less they bother pinging the map, mostly because they feel like everyone is like them and watches the map. Also you don't need map awareness to call your mias just watch your lane....
-Stun range is not a major factor because its not like you have to guess it the game shows you the range already.
Not your stun range, the stun range of that taric that keeps raping you everytime you try to LH. This video explains why you should know stun ranges / snare ranges / slow ranges etc.
-you have to first know how to play a champ to know what items you should get for the champion.
So you have to know how to play ashe before you get that banshees veil to counter that annie that's always raping your ass? wat?
My point is you have to know when to get in a fight and when to run because if you feed the game becomes quite GG and if you play it safe and get kills without dieing you become fed leading to most likly a victory unless you screw up or you have a horrible team.
Kills are not the only way to get fed, I usually have more gold from farming creeps than the 8/0 tryndamere taking top lane.
Knowing when to run also is apart of map awareness you have to understand that when the enemy team is missing you should play more defensive and less aggressive
Valid point unless you play nidalee / shaco / eve / twitch (assuming they don't all have oracles).
