Four General Rules That Will Help You In Game

I have been playing league since 2013 and while I am no great League all-star but I do my part. During my play time I have noticed simple rules of thumb that pros take for granted but should probably be written down. These rules can be followed at any level and any skill level but will result in a much cleaner match for yourself.

1. Ward is not a dirty word At start most player pick up the "yellow trinket" or warding totem. This item grants a small ward for about 60 seconds and has a 120 second cool down. USE IT! Wards are one of the most important part of league of legends and the more your team has the better your chances are of finding lone players out that can easily be killed. Or prevent yourself from becoming one of these easy kills. Furthermore don't use only the trinket buy normal wards, sight-stones, and pink wards so you can keep the vision going. At level 9 go ahead and upgrade your trinket so now you have free wards. It's everybody's job to light the map up, do your part.
2. If you see it ping it If you see an enemy on the min-map that is not where he or she should be ping them so your team can know. If your team already saw it there is no harm done, however if they didn't see you possibly just saved them.
3. 15 seconds or drop it Don't chase any enemies alone for more than 15 seconds unless you can see the whole quadrant you are chasing them into or all 4 of the other team. 15 seconds is roughly the time it takes for a proper ambush to be set up or help to scurry from one side of the map to another. If you are alone don't be greedy you giving the other team one kill and who knows how many assists is far riskier than the reward of one kill.
4. Creep waves are a river, control the flow Minion waves or "Creep waves" are a fundamental mechanic of League but for some reason after the lane phase are ignored by players unless they need gold and have free time. Do not do this creep waves push one way or another when they are left unchecked make sure yours is pointed in the right direction BEFORE leaving the lane. If your mid roaming down to bottom for some kills at least get your lane pushing before doing so. This serves many functions such as denying your lane opponent creep gold by pushing them into their tower, buying you time so they can't simply shove your tower down while your off walking in the woods, and finally if your lane follows you down your creep wave will get free damage on their tower resulting in you getting a leg up without even being there.

Here is four rules I check myself with every time I play. I get to high level players this is very old news but I figured there would be no harm whatsoever in posting it here. And I do know there are pointers I missed or forgot (can't remember some unless I'm in game) so feel free to add your own. Who knows we may all surprise each other with some new easy tricks.
