Yeah, it isn't reasonable.
It's never reasonable to expect to get all the rewards without putting in serious work and even dedication; if you're not going to put in effort to
earn the rewards then you shouldn't expect to get them.
I agree in principle, but I don't agree in relation to Gwent. First of all let's define "casual play". If you can play for an hour or so almost every day, then this is not casual. If for various reasons it is only possible to play a couple of games a week, then perhaps Gwent is not for you.
But even 1 to 2 hours per day is not enough to get the achievements, rewards, resources etc...
Gwent seems to cater to people who are on youtube or twitch, who can play 5-7 hours every single day. For everyone else it becomes a GRIND. You only need to look at the contracts and rewards to see this.
The GG contract: give 1000 GG and get 3 keys. Give 5000 and get 5 keys. For the mathematically challenged such as myself, that means playing another 4000 games just to get 2 extra keys! How long will it take you to play 4000 games?
The level contract: the rewards become more interesting after reaching level 60 for the 6th or 7th time. But then again how many games will you have to play to reach it?
The irony of it all is that, if you do get to play so many games and finally get those rewards, they will become meaningless. This is because by then you will have managed to collect most, if not all, of the cards already. You can see this with popular Gwent players on youtube; they have 100.000 plus resources, but they already own every card in the game. Do you think they care about Journey?
What also bothers me about the rewards is that often are just cosmetic. After putting in so many hours, a title or a silly avatar is not what you are looking for, unless you are 12.
Gwent is a nice game, but it takes too long to get keys, and in Gwent keys are key.
Journey speeded up the process considerably, but otherwise keys only come through grinding.
No one expects something for nothing, but unless you are willing to spend money, then you must be ready spend hundreds upon hundreds of hours to be able to get kegs and craft cards.
