Your Biggest League Pet Peeves

I'll start things off with some of mine.

• When I'm hard-countered and at tower all laning phase, yet get zero jungle help.
• When I spam ping MIA, and even sometimes ping the expected path of my enemy laner, and still wind up hearing "an ally has been slain" once they reach the lane they're roaming to. Bonus points for when their entire route is warded.
• When you play one of my mains and feed.
• When you ban my intended pick with the excuse that you weren't paying attention.
• When the only threat(s) on the enemy team is AP and nobody buys even the tiniest bit of MR.
• When our jungler feeds their laners by a) going in for a gank on low HP or b) repeatedly ganking the already snowballed lane.

That's all I can think of off the top of my head for now.
