Things can be broken with numbers, that's why specialists are pretty easy to balance since all you really do is pretty much change the number around statistics and that's cool.
Generalists are hard to balance since it involves so much more than just numbers.
Not to mention, WW's true counter is half missing from the game, grievous wounds, that's a problem by itself too, but to say that WW should be kept weak because of Riot's own incompetence? No.
Also I never get the idea why people always put Garen to the easy to play champs, have you actually played him? He is so much harder to play with all things considered, why?
- Firstly while designed to be an early powerhouse, his early really isn't amazing, at least not now,
- you have 0 lock down nor instant mobility so you have to purely chase with running along with some help from MS steroids and a silence, nor are your bursts spectacular to begin with
- your cs'ing sucks but you have a spell for that which instantly pushes waves for you leaving you open to be ganked
- you have an ulti that is really good in killing stuff, but you don't scale EVER. Making the incentive of using it completely redundant.
Garen is only good in taking damage, that's all he fkn can do. What can Lee do? You tell me.
You see the difference between high and low skill cap champs now? Not matter what happens, averagely, high skill cap champs will ALWAYS be more useful than low skill cap ones, unless ofc, the favours fall completely in them low skillcap's way, which ofc they have to EARN it. Unlike high skill caps, their overloaded kit is BORN with them, you just need to practice and nothing more, meanwhile low skill cap champ players have to play with their limited kit and potential and adapt from situations to situations.
To summarise, high skill caps have versatility, low skill caps have numbers.
To say that high skill cap should also be numerically stronger than low skill caps, just no.
If you buff Garen he may dominant B5, ofc he will, but in pro scene he would actually have a chance to get picked and sitting in an actually balanced spot other than being this piece of shiet he is now. I am not saying that you shouldn't cater towards low elo players but if you balance the game around that level, you're asking for a boring and completely static high elo scene, which ofc, we already have it.
Go figure.
EDIT: Also Lee has 2 instant gapclosers (3 if you count flash) for the initiation, WW has to physically run to you (or burn flash) for that to work and he is suppressing himself in the process too.
