Support item and adc starter item that make them split gold from kills and interactive affects.
Riot games has had a lot of problems with bot lane balancing / gold income. The main reason for this is support makes a huge amount of gold but if you have a support, adc item that bind splitting kills from kills like %70 adc -%30 support even if the support gets the kill. This type of item makes it so bot lane can put more effort into teamwork. This also enables u to make upgrade items with unique effects between the adc and supprt/ (tank item that makes support take all lethal damage from adc for 1 sec and gives support 1 ranged shot both on cd. mage item allows adc to slow on active and mage gets spell that slows. Utility item for adc gives increased attack speed or move speed boost and support gets spell that can move support a short rang to adc) These are just idea's but i hope that changes like this can bring bot lane into more of the team lane. Looking forward to future patches keep up the work. :D
