One button champion

Just had a game against a 300+ matches Tryndamere that was playing with Flash+Ghost. I was Hecarim, playing as a jungler... My top laner picked Pantheon so he could counter him, but guess what, when the game started this 300+ matches chicken swaps with their midlaner to avoid Pantheon, but in the process he fucks our mid-laner. I actually took FB in my first mid gank. But it was very hard for Nidalee to 1v1 him, so she had to swap everytime with Pantheon (losing a lot of CS+exp, while Trynda could get free farm). But guess what ? When TF's started, he could literally 1vs5 us by pressing one button.He ended up with a score of 15/15/X. He actually carried that game, because we had to fucking use everything on him everytime he came to 1vs5 us.He even crited me for 1.8k dmg basic attack.

I usually like to play more mechanical complex champions. What i hate the most is this :

You are a experienced Tryndamere main. You know you picked him because he has like 0 skillshots. And even after this, you start running like a chicken just because you think Pantheon could counter you ? It's just like my main Aatrox. If i pick first top, i usually end up playing with bad Jax/Renekton counter wannabees. And when they start losing, not even they counter me, but they start building mega OP builds like NINJA-TABI/RANDUIN/THORNMAIL/FROZEN HEART. LOW ELO forever for those kind of players
