@ any Rioters, why don't skirmishers have their intended weakness?

You guys classified roles in order to facilitate discussions of characters through those lens, so here we go. Lets talk about Skirmishers.

According to Riot, Skirmishers:

> Unlike Assassins, Skirmishers aim to shred through any nearby enemy that approaches. Because Skirmishers lack high-end burst damage or reliable ways of closing in on high-priority targets, they are instead armed with situationally powerful defensive tools to survive in the fray, along with extreme sustained damage to cut down even the most durable targets.

So they are made to kill EVERYTHING, possess powerful defensive tools and have the games highest sustained damage.

Their weakness is supposedly low burst damage and no reliable way to gap close.

The skirmishers of the game are

Fiora Riven Yasuo Tryndamere Master Yi Jax Ekko

See the problem here?

Most of these guys have ways to instantly gap close and all snowball more easily than most champs into fed states where they gain extreme burst damage.

What gives riot? Other characters that aren't supposed to burst simply don't burst unless extremely fed.

Lacking reliable ways to close in on high priority targets also doesn't really hold true here. These guys mostly have gap closers that go through the front line.

They may get stomped after running in, ( they snowball so hard who knows), but they still ultimately have an easier time reaching their target than other sub classes that don't have this as a clearly defined weakness.
