They are never just straight buffs to tower durability and damage, which is what the majority of players want (?).
Instead the towers get 300 more hp which is like, 3- 4 autos worth of more hp which is fine but now they take more damage from minions. So its a minor buff with a minor nerf and then, minions get a whole 25 more movement speed when near them, which is an odd change Imo. Why can't towers just get more armour or straight up durability? or more damage.
I just don't understand. It feels like Riot doesn't want to buff the towers so they give them a small buff and a small nerf at the same time just to make the player base think they are trying to make towers better.
