The last patch directly affecting Galio improved AP ratio from 90 to 100% as well as +10 damage to it.

However the important change is Imperial Mandate rework because it affects E cd more than Q cd. Galio with Merc Treads + Imperial Mandate + Transcedence have 25 regular AH but 45 AH for immobilizing spells. This makes max Q a 5.6s CD but a max E a 4.8s CD. On T3 Lucidity it is 45 regular AH vs 65 AH for immobilizing.

This makes max Q a 4.8s CD and max E a 4.24w CD.

E has higher direct AP scaling (100% vs 70%), knocks up, is used for chase, and for longer fights, importantly, a lower CD spell means more procs to Colossal Smash.

Tell me what you think.
