CertainlyT's champions has killed the balance team.
These overloaded kits full of flash and flare he builds have an insurmountably large number of variables that have to be fixed and fiddled with because they're so full of flash and flare. So the balance team has given up trying. They just let stuff sit, show up to work every now and again, nudge a bar left or right and call it good. And how do I know? Because level 6 WW deals 165 bonus true damage on his ult with Skirmishers passive, and they saw that in PBE and went "Eh. Whatever."
