Most games are badly designed, that's why the optimal way to play them (meta) is often unfun. In general you want interesting, meaningful, fair, fun player interactions in your PvP game thus you are supposed to design your game with those in mind. A game designer should be an experienced wise gamer preferably in the matching genre (You don't want mmo/rts devs with 0 fps experience designing a fucking shooter) because a proper gamer is the only one with perspective to design games properly. But what happens in real life is designers are hacks who just mix random shit together they thought it was cool at that moment ("What if dash? What if parry melee? What if wall jump?" - icefraud the one trick pony trying to design gameplay of deadlock) . Designers are not at their position for their merits as gamers, they are there because they are sell outs. With these in mind it shouldn't be suprising why pvp games will always have shit metas. Game designers are just suffering from skill issue.
