The fact is that playing to win is the best way to climb. Many players who focus only on stats who are trying to win fail to work with teammates because cooperation's a harder metric. Champions like
and mages with high AOE can easily rack up very high kill participation % compared to say a split pusher or duelist champion.
Win or loss is consistently the best metric to measure skill objectively. Not only does it show when a clear mismatch happens it doesn't make some one look like a much worse player for experiencing that mismatch. The RNG of factors like playstyles, teammate,s etc is filtered out by the simple fact the single constant in each of your games is your in it. Proxy style strats like what we have seen with Sion and Singed are completely focused on OBJ control even at the cost of stats like KDA and Damage.
People seem to forget that stat padding is easier then winning. Any time you can cast an ability or add a single tick of damage you do it. Preserve kda? Abandon any risky teamfight and avoid being the one who engages, especially if you don't have a wall of allies to use as meat shields. Constantly burning every ability soon as its off CD and backing when OOM or at any HP value your at risk of a death will make your stats better and it takes almost no effort.. Spamming wards all over the map will add vision.
Lets take a
stat padder. You get a better CC score if you use R every single time you have a target you can hit. Follow it up withan auto EQ and back off and your damage goes up. Meanwhile some one playing to win is going to hold onto the R for when it will matter and sticks around for a fight. The stat padder has an opportunity to add damage and CC every time there is a target in range but a good player holds it so they can make a impactfull play not artificially add to their numbers.
A stat padder will take any and all CS, you grab it even if your teammate is behind or near their next power spike. you don't care that letting some one get a completed item will help your team you want the most gold most cs most damage best kda… not a win. You play selfishly and it fucks over your allies.
A lot of players pad with out meaning to because they only check metrics tracked and not if they are making mistakes. They don't consider how to help a teammate just if that teammates numbers are good or bad.
Its a shit attitude for a game like this but its very common and folks don't always understand why its not productive. Skill in a team game is not just about you, your lane. Its about interactions with the other 4 blokes ya got around you.
