Its a moba. Theres never "balance" . Turns out when you have numerous packable champions with varying kits some stand out and some are subpar. Like you know, fighting games, Mmorpgs, Mobas. best you can hope for is that is that ever class and every champion has a home at some mmr or in some meta per season.
If you have low skill cap champion they cant be as good compared to high skill cap champs. Look with the utmost honestly I can say that As it stands, the majority of player base can play anything and climb if they are good at what they play until they hit a ceiling that cripples them... at which point hey your hovering at 50%.
You want everything good, always in any and all mmrs? how's that realistic?
You want everything at 50% win rates? how is that realistic?
You want everything on the same power curve and same best case regardless of mechanical difficulty? how is that realistic?
You want 100+ varied kits and appearances to enjoy nearly equliventpick rates? How is that realistic?
You judge balance by only the top 0.5% of the games picks? how is that realistic?
By all means I invite you to clearly explain what the hell your talking about when you demand better "balance" What do you measure it by cuz most players use a mix of the above and its dam stupid to set as an expectation. If your an exception id love to hear it.
"Balance" is vauge term and balance is a trash term for mobas. You want to make the game better or want to discuss what makes it better. Talk about game health and remember to approach it as a variable by mmrs. Turns out player skill has an impact on champions best cases.
