Tank's Meta and New Runes

I came from a game with my main account and i want to ask so many questions as the days goes by, using the new runes. Many people say that now the game is balanced somehow. Well lets see... After i saw cho gath on enemy team i thought of picking jax. I had a lot of days to play this match up and i remember from old games that jax goes well vs cho gath. I could even say that jax is completly counter to that tank. But season 8 is here and a lot of things changed. Counters has changed. We started on top lane. It surprised me that he took first blood by going insta-agro in the lane AND inside my minion wave with only a dorans shield. What could i do? Who runs back at lvl 1 when someone is fighting you inside your wave? So i stay to fight him and i was dead in a few seconds and he was almost full hp. Cho gath at elder patches had hp regen. Also from his passive. But now the things are changed. He gains hp :

1. From his passive
2. His E
3. And of course from new "op" runes. (like everyone say) I decide to farm up and ignore him. But he was able to cut half of my hp just with E. Anyway at lvl 5 i had some damage and he had only a catalyst. That means : i came back to lane with rised stats (building damage) and he had a catalyst (no damage, no ability power. Just Hp and Mana). Guess what happened? Level 6 with 1.4k Hp and i was a snack with not-even 900 hp. Untill the end i was 3 hits (even with E or ult activated) 1 Q and 870 true damage from his ult. So that means he didn't have to fight me. He could just auto me and ult me. There are so many examples to mention, so many cases, matchups. I see youtubers playing games and showing the new runes system. At the end all of them are like "Thanks for watching guys, i suggest you to try this champ-this runes, its really really fun" My questions are : Where's the fun? What can you do in such games when you cant even aproach to gain the exp (not to mention what happens if you get close) You build damage - you have 0 damage. They build Hp - they almost oneshot you by casting one time their spells. Just with their base stats growth. Where's the balance? Im not having fun by looking this. I dont see anything "funny" when a champ like this can "win" you. I dont think that something is "funny" when im losing and somehow when im winning (most of the times at least).
