To be fair, I can see both sides.
However I also agree that giving the player more cards to draw prevents people from just forfeiting if their first round went bad, they get the feeling they might yet be able to turn it around. A simple card with a good ability can change the entire game. For example, if you get a card that allows you to play an additional card from your or your enemies graveyard and the card you draw has the ability to draw an additional card from your deck that would be a possible win-combo.
But here is the crux, and that is the dilemma. You can change a game in an instant, therefore even precise and intelligent planning can be thrown over and not pay off due to the enemy having an incredibly lucky draw.
What makes Gwent unique from any other game I've played isn't so much how many cards you play with, but the idea of rounds. Yes, you have games in tournaments that will do a best of three formats but you get to draw a whole new hand when you do that. With Gwent though, every round matters and for different reasons. The first is the most important because it dictates the rest of the game of course and your options are the most open. You can either go in with the attitude that I will play aggressive and look to win the roung (if reasonably possible) or play passively where your goal is to force your opponent to play as many of his cards (the big ones especially) hoping that will pay off in the next two rounds.
That essence of looking at your hand and not only planning how to win that round, but also what to do for the next two, is still very much there. The bonus three cards (assuming no extra card draw mechanic) can influence it yes, especially if you draw the right cards. But to me the most skilled player will still win because he will be able to bluff his opponents to playing those right cards at the wrong time. It's why if I'm a monster player and I have Geralt and a Scorch card, then I'm dropping Geralt in the first round.That's because I'm betting he won't have that card in hand, so he's going to be forced to play a couple of cards to get past me. Then the next round (depending on what he plays of course) I can use scorch which wipes out my little horse and guarantees I have Geralt for the next round.
What I described above is something I'm not going to find in any other card game because with those I'm relying on the fact that I'm going to draw the cards I need. With this one, even with the addition of three more cards you still have to rely on what you got because you can't count on the cards you draw to save you. And if you are, then more often than not you will lose.
