A nerf that thunderlord's decree needs..
Don't let ranged champions be able to proc it with only auto attacks.. It makes the early game for melee vs ranged kind of unfair in my opinion.. Just make it so that you need atleast one ability within the 3 attacks to proc it.. melee's are unable to avoid being right clicked.. You could even make it to the same for melees that's fine.. but I feel as though it gives more oppresiveness to many champs early games.
EDIT: Some clarification here.. 1. The trading power early game is really strong... but 2. There are 9 key stones in the game.. but yet I'm still seeing on average 5 thunderlords per game.. I want diversity dammit!
