Just watched a challenger game...
It was a freaking clown fiesta.
Towers died quickly. Tanks died quickly. Baron/Elder died quickly. There was a 10 minute gap where no one tried to fight because no one wanted to be the one to lose the game. The team tanks purchased GA even though its a "adc item" that neither adc purchased... The team tanks also took only damage masteries.
Champions died so quickly that I couldn't even tell what killed them unless I slowed it down to .25X... even then it was hard to tell what they took for damage. They literally just went poof. I'm not sure how these types of games are supposed to be exciting to watch (or play). There was no spectacular wow they did a good job killing that guy, there was no see-able strategy except stay out of range or kill the enemy instantly.
Please lower damage on everyone including the tanks. But please don't lower tank stats just to balance them having high damage, just lower the damage.
