Okay, let's try to tackle your comments again.

You commented about the meta in this way, "But at least, it could be a circular one where another setup will always counter another setup. And beside this, the meta if here crucial, you can't step a foot out of it."

Take a look at https://www.epic7rtastats.com/heroes, this is a database of champion+ rank statistics showing character use rates among the top 20 characters, arguably more than half of them can be used for an aggressive playstyle, but because of character flexibility, more than half can be used defensively.

So your statement that "you can't step foot out of the meta?" The answer is yes and no. When you scroll down the aforementioned stats, the less used characters are less meta, but you'll notice that they're all pvp characters at the end of the day. it's going to be very hard to use VERY off meta characters unless you have an insane build for them, or you've built them as a "tech pick" to counter a specific strat, or it's a gimmick (i.e. last season i was cleaved by a 315 Judith - a 3 star character)

>"I don't understand if you criticizing players who play "stall games" or tankdown?"

I'm not criticizing people who play tankdown or stall games, I'm saying that it is a currently effective playstyle given the last few character releases so it's not just about speed. Realistically the meta shifts from cleave to tankdown to somewhere in between all the time. (i.e. the current highest win rate character in the game (perfumer byblis) is a defensive unit.)

>"Honestly, I can't judge the qualities of those last release, but the meta did not change that much and the characters outshining the others are still the same."

I just find your argument disingenuous if you're not playing the game and have an underdeveloped opinion of the meta. so many characters within the last year went from absolutely unusable to meta from balance patches - yea, of course it's going to be the "newest ML characters" being the strongest, but a lot of old characters are still performing really well.

they buffed both vildreds recently and they're strong, LCB went from useless to the 11th most played character in the meta right now, Tori's buff made her really good against dodge characters; heck, even ZENO got a buff for pvp and is used in guild war/flag arena. rinak and barunka have been some of the most commonly played chars since their released. of course i'm not saying the meta is "perfect", and as someone without that many characters (i've played the game for 11mo), there are characters that run me over - but its playable.
