Towers need to be strong enough to defend against an immediate 4-man dive at level 6
This pretty much shuts out the remainder of the game if one team hits 6 before the other, as it snowballs out of control with minimum one dragon and two turrets at minimum. More likely it's also going to be 2-3 kills, and sometimes even three turrets.
If one team hits 6 before the other, there's no way to counter this, and a single mistake made in the first couple of minutes of the game should not be the deciding factor.
Can this please be addressed before the season ends?

. Also, most of these plays of 4 man gank bot is after they have a lead, meaning they can likely dive with minimal consequences, and if they are going botlane, botlane likely does have a lead and needs to be ready to evacuate or cc effectively, trying to prevent the wave from reaching turret is not heavily effective. If your a jungler, you should hope your actually smart enough to prevent counter jungling, and effectively feed yourself for this maneuver. Lastly, If the 5 man is not challenged, and has taken the turret, you can ADDITIONALLY, lose ANOTHER turret, dragon, or a champion kill if they can get an effective lock down or botlane has failed to recognize an obvious retreat sign.
effect to sustain a large number of attacks from certain people trying to rush first turret bonus. 4+ people turret gains increased damage and bonus damage reduction, makes team fights actually necessary, and team-wide lane control without mindlessly pushing lanes as a team.
