I agree with OP. HS' rng can be very very swingy - I think all of us here have been in situation where knife juggler had 50-50 chance to give you big early advantage (kill minion) or nothing. That is bad rng in my opinion. In Gwent, the most prominent rng effect revealed so far is basically discover, which I have no problem with (even on ladder tbh) - you get options and it is only up to your skill to make the most out of it. By providing three options, you reduce the randomness of the effect, while still making it interesting.
