this game is heavily pay to win, i already reach pvp arena rank score 910, its a rank diamond 2.
my team is quite good all member of my main team are evolve to 3 star and they are 2 SSR 1 SR and you will often meet with all evolve to MAX STAR. to evolve you need collect the hero's piece from recruitment, and the number isn't small.
at this rank skill player doesnt matter if u face some one at MAX STAR DRIVER/HERO, they will just 1 SHOT me and i am dead even their level is lower, to get 1 shot is very easy just stretch your aim to the maximum, wind doesnt matter anymore.
if u are a pvp player, you need to be a whale 1st, your skill wont matter until you meet someone at your lvl of whale.
conclusion if you are hoping a battle of skill similiar like worm or gunbound, its didnt exist in high rank unless you are a whale that can compete with other whale.
