Ekko adjustments on the 6.11 PBE
I think they are definitely headed in the right direction. Though looking at the suggested value the slow ramp on Q per 100 AP seems too high, since you can get 100% slow with 700 total AP.
Most likely the developers are doing some boundary testing to see how a round number like 10% feels and will dial it back if it is too oppressive. Won't be surprised if the slow ramp ends up in the 5% - 7% range when the patch releases in a couple of weeks (giving it +35% - 49% additional slow if you look at a 700 total AP Ekko. Opposed to a +70% additional slow).
Some other balance changes that seem extreme in the notes, but not talking about those, just the Ekko adjusts.
