You kinda already said it, but let me put it more clearly.
The more consistent the game, the more difficult it is too balance. LoR/HS/MtG already tries to balance the game with RNG, which works up to
a point, but still not enough. Yet, Gwent's balance by RNG is minimal
(and players still complain *cough* Bribery *cough*). We should be glad, except for the fact that CDPR cannot or does not want to balance the game. Instead, they tune a new deck every season and when that one goes overboard (which it does), CDPR nerfs it and puts another one in its place.
This is strictly
FALSE. It is very difficult to balance a card game through RNG, as will be shown in a mathematical example.
Proof:
Suppose that each faction has 2 cards that vary in power level, compared to other cards in the deck.
The table below denotes the power level of each card. As example, deck A, has 2 cards, that each play for 5 and 6 points respectively. While deck B has a weaker seperate value of each card, 3 and 4, the
combined value is assumed to be
15.
Table below denotes probability of outcome of different events. As example the probability of both players drawing their cards is 25%.
A/B | 5,6 | 5,0 | 6,0 |
3,4 | 25.00% | 9.38% | 9.38% |
3,0 | 9.38% | 9.38% | 9.38% |
0,4 | 9.38% | 9.38% | 9.38% |
Hence under these assumptions, we can summarize the probabilities, and determine the average winrate for deck A and B.
These are
Now lets assume that developers decide to improve win rate of deck B by buffing the value of one of the cards.
A/B | 5,6 | 5,0 | 6,0 |
3,5 | 25.00% | 9.38% | 9.38% |
5,0 | 9.38% | 9.38% | 9.38% |
0,3 | 9.38% | 9.38% | 9.38% |
Hence in the scenario where both players draw 5,0 and 5,0 each have 50% chance of winning, or 4.68% respectively, which is the chance of winrate deck B has increased by.
The tricky part is that there are way more cards in the game, and with availability of tutors, the math of determining these probabilities is way harder than any of us is capable to immagine, or put into a mathematical model.
Thus the most reliable method to balance is when both players draw their cards, and that their power level is equivalent in terms of points. Even then, the game wouldn't be balanced as tech options are a thing, and some decks are more susceptible to techs than others.
Please stop spreading false rumors that this game needs to be balanced through RNG. The likelyhood of achieving this is small compared to removing RNG entirely.
