I remember having a game as Orianna mid with Sion support that had Kai'Sa ADC. When she started dying a lot in the mid game when he started taking her kills intentionally and leaving the lane for no reason, he said 'go main supp usless' - his literal words at about fifteen minutes.
And just by that, I know that guy won't leave bronze or silver anytime soon. Every role exists for a reason, and his, as a support, is to babysit the ADC and then entire team when it comes to the mid and late game. To be honest, I believe he either never counted or never realized how many times some supports he played with saved him.
If you play support right, it can save your teammates with abilities or right-placed wards or give them kills they would never get otherwise. However, if you want it to be fun, it depends on what champions you play when you play support. If you play tanky champions, like
,
or maybe
, you need to be in front of your ADC most of the time because you are tanky, so if they get targeted, it's better for you to lose a little bit of your health than your ADC losing a chunk of it. So yeah, you don't really do anything besides farming with your Relic, watching out for your ADC and ganks. Oh wait, that actually takes focus!
As for mage supports like
,
,
,
itd, then your job is to harass and shield, so if want to spice it up a little early game, I suggest you try out champions that fall under this category.
is a hybrid of a tank and mage, so as much as you can poke the enemy laners, you can take much more damage early that someone like
or
. In this category, I personally enjoy
and
(and yes, I know Lux isn't really a support, but whatever, she's fun) very much, because I know how much enemy can tilt there, hehe.
So, for anyone who goes around saying support is easy or useless or shouldn't exist, you try playing a support listed champion with a bunch of kids telling you what to do even though they don't know what to do themselves. Two words - suicidal Vaynes.
And for anyone who says support is boring, just try different champs and see for yourself. If you still see it as boring or useless, then don't play it. Simple as that.
