Riot, I have an idea for how to fix skirmishers without making it trash
Riot now your "fix" just destroys the point of getting skirmishers, since the only people who were getting it were AS duelists. Making it deal the true damage over three seconds when it only has a 6 second window is pointless.
Heres how you fix the problem, because other than Warwick abusing it, it is fine.
Make it so that the damage cannot affect the target more than once every 0.5 seconds. Warwicks ult ticks once every 0.3444 seconds, so it keeps him from abusing it, while also keeping it in a good position
similar for what you did with Shyv and Tiamat/hydra
