always push an advantage no matter how small.
Just because you are a healer support doesn't mean sitting on your ass keeping someone alive is a guaranteed win.
-After winning trades keep the victory going by using autos, or point and click damaging spells whatever gets the job done. Just because you won the trade doesn't mean you won the lane.
-Don't just toss shit out when you have it off cooldown
and
players love tossing their bubble or tornado out for no reason wasting their mana and cooldowns when it is needed.
-FOR THE LOVE OF GOD stop using exhaust near the end of a fight. why is exhaust being used when someone reaches 10 hp STOP THAT. use it mid fight to change the tide of battle. exhaust is for mitigation not saving.
-look for the most important person on your team and protect them at all costs. ADC is not always the important person to protect if they are trash they are trash.
early lane phase is actually dope now. toss it in a bush after you win a trade or at the very start of lane phase in the bush closest to you and clear out the beginning yellow trinket for an easy 5 gold 10 gold if both of your opponents do it. its also a nifty pseudo shield if you walk over it sometimes people will attack the ward instead of you.
-just because you are a support doesn't mean you can't stop objectives. If you see a rengar with 30% health trying to do a dragon just poke him and make him go away or die. But don't chase that shit will get you killed.
