guess is just a matter of opinions
im playing cuntwars with 2 accounts (what i call main and secondary one that used main code), after three days my secondary account got way better army then primary one (but im also stuck on a full epic line of 4 box with a 24h cd on the main account in pvp), while my main account is stuck on league 20, the secondary is getting not many problems to stomp stuff (got lucky on chests). But again is a temporary moment, because you may get lucky anytime with pvp chests and you can always decide to sprint for the win by using the powder of enhancement to actually gain a bit more into the ranks (which im currently saving).
at least in this game when you have done your dark tower / you have all chest full in pvp / you have done all your journey / your done with guild war setup, you can still farm brawl with no negative conseguence whatsoever, for extra card/coin/stuff... no other game i see on nutaku has currently that option since all are based on a stamina effect (making them way more "p2w" or wait for do something based
).
Of course you will get killed once you reach league 20 by higher level decks but still your able to progress on a steady way, so i cant really agree on your statement
but again it's just a matter of opinion i guess
