Looks like we have different impressions of card games.
Your goal is to get as good cards as it gets - this is the common purpose of TRADING card games. However Cabals is not a trading card game, there's no trading involved here, it's a Digital Card Game: like Shadowverse, Hearthstone, Faeria or similar titles.
There's a whole different premises on the business model:
Trading card games encourage players to collect and trade and usually print cards en masse (which we can for sure say is not happening here).
Whereas online card games are less focused on the trading aspect, but more on gameplay.
Digtal card games create a competitive scene and encourage players to to play different decks - meaning money not through flatout better cards, but selling a lot of different ones - this is for example why official tournaments have rules like "decks from three different classes".
The idea is to allow players to not feel disadvantaged and avoid making playing feel like a grind, but instead saying "hey - you can play a fair game and if you progress you get more cool stuff to try!".
Those are the basics - let's skip right to the biggest wrong in your argumentation
"Shadowvers's publisher is knowing for their games being nothing more than pay 2 win".
This is literally the most false statment I have red in ages - Shadowverse gave around !!!!!!49 completely free booster packs!!! to new players and regularly hands out new ones, it's known to be the most generous game of the genre - just enter it into goggle and you'll see:https://www.google.de/search?q=shadowve ... e&ie=UTF-8
Shadowverse has build a HUGE playerbase within less than a year simply because the sheer amount of free stuff you gets allows you to build your first equal-competitive deck as soon as you start. Your goal is it to gain more cards and more deck, not endless grinding to get a single viable card like it is in Cabals-Elite-Meta.
And by that modell they made 100million$ in 6 month, the numbers speak for themselves.
Shadowverse is the leading example how to make money in the Digital CG-genre AND please the customers at the same time, while breaking into a market where Blizzard had a completely monopoly and insane market power for YEARS.
Cabals has been around even longer - but hasn't gotten remotely close to what Shadowverse managed to do.
And it's not because of gameplay, it's because of marketing and income models. Cabals is as good of a game as Shadowverse.
It's just simply not accessible for the majority of players (who want to play DGCs not TCGs).
Cabals now has the chance to turn the wheel around.
1.) You assume that Cabals patch speed won't change. Steam releases are known to get a Ton of upfront money, if this is invested in further developement games like Shadowverse or Faeria have shown that they get a LOT of more income in the long run. If Cabals does its entrance right Kyygames can easily increase their capacities
2.) Nobody said that they have to get a full collection. Getting a viable deck of a single Cabal is within an acceptabe amount of time is enough. There's 5 more Cabals for people to gain cards for and invest money in this. Card games are not grind MMOs, where you have to stick with 1 character forever.
DCGs live through variety and offering it's players different decks to try and strategies to use.
3.) Given the daily grind and 30 rares per month you suggest that players would need several years to get a full Elite (= "equal-competitive") deck. The majority of players won't stick with a game that long if the are forced to grind and don't see variety.
You are obviously a mobile player who has much more tolerance for these policies, believe me that most steam players don't.
4.) As for your statement "the playerbase is fine it is", sorry that's a short sighted perspective. Kyygames is a company and the primary goal of a company is getting money - which again is gained via increasing its playerbase. If your position was correct the case they wouldn't have invested so much time and resources into the Steam client to begin with, in an expanding market betting on a status quo when other companies expand their market power and new competitors enter the scene is completely unreasonable from an economic perspective.
