TANKs & APs

I did play lol for a few years and i think those tanks are way too op in the games. This game is not only for WCG, but also for all players who played this game. So, i believe those tank items should be much more expensive. Also, for APs, we should cut the damages from APs, damage of the skill should be lower than 50% of the total AP items. Cooldown reduce should be cut to 20% from 40% before. For some champs, nasus, the cooldown of his W should be always 25s
