Would it be too bad(gamebreaking) if there was a mastery tree related to AI units?
Imo it would be cool having masteries which help minions, turrets and stuff. Here are some mastery and keystone ideas(nerf or buff them if you want to). Leave feedback and tell me if you like the masteries, which one do you like the most. You can also create similiar ideas and leave them in the replies :)
March Leader: Nearby allied minions gain 1% movement speed. Reinforcement: Nearby allied minions take 1 less damage per 100 health lost from enemy champion basic attacks and spells. **Garrison:**Nearest allied turrets gain 20/40/60/80/100 attack range. **Nature Boy:**Gain 1/2/3/4/5 movement speed in jungle. Doubled in river. **Scuttler's skin:**Gain 0.5/1/1.5/2/2.5 armor and magic resistance for every Rift Scuttler killed(Can be killed by ally champs if you are near them) **Thief:**Deal 0.5/0.75/1/1.25/1.5/ true damage on-hit to jungle monsters in enemy jungle. Keystone - Jungler's Wrath: Deal 0.11%-11% increased damage to epic monsters based on their missing health. **Keystone - Turret's Might:**Nearest allied turrets deal true damage. Allied nexus turrets get their damage converted to magic damage when attacking super minions.
(Nearest turrets means that both nexus turrets will gain the bonus, but in lane only the closest one to you gains the bonus)
