Should Riot implement negative stats?

League has turned into a really fast paced game due to low cost and high value of items,and sadly there is no counter picking anymore.Be it items or champions.Its mainly who gets the upper hand/has better positioning or just plays better in some rare cases. Many champions especially the new ones are overstuffed with many different over the top combinations of mechanics and the old one cant keep up with. Every player build the same items and runes and has no problem winning against any kind of response of the enemy team. Roles mean absolute nothing and league is still a nuclear war zone.In a western duel the faster hand win here its the same thing.

So what if there was a way to adapt to these situations? What if high level items gave negative stats? What if you with the choice of role gained positive and negative stats for specific role? With a system like this you could gain high damage but be a glass cannon or lose damage and be more durable.Have more sustain but lower pools.lower cool-downs but higher costs.A balance act of power gain. Also items shouldn't be bloated with 4 different stats.Its unhealthy and provide so much for no cost.Having only 6 items slots should make you consider how you play and how you react to enemy play.It makes you flexible and can surely be more interesting than doing the same thing over and over again.
