The game needs some class work

Games suppose to revolve around a series of checks and balances. Range>tank,bruiser, assassin>range,burst mage, tank>bruisers,assassin, bruised> squishies. The problem is though there is a pretty big despairty in the power gaps and effectiveness of each role. As it stands top lane is by far the weakest role with the least impact on the game. The majority of the roster apart from Jax and Kayle lack the strength needed to survive and be impactful in the late game which is an issue. The power a mage, adc and assassin posses is far too great through out the games entirety vs the tank and bruiser. This concept of falling off isn’t something that should exist in the game and instead only be factored in when you die in game. In all honesty something needs to be done to make the game healthier and give each lane a chance to carry rather then it only being the 3 primary roles mid,jung,and adc. If anything defensive stats need more impact as the roles of the tank and bruiser become more blurred since they start dropping off all around and losing impact. If anything bruisers and tanks need more resistance all around so their presence can be felt especially one that has done well cause being after 15 min you tend to get get weaker as bruiser (unless your Jax,riven, and mundo) we need a good phase out stage where defensive strength increases highly toward the later levels
