Legends of Runeterra. No RNG please.
So I was hoping this card game would be different than all other online card games. It definitely feels really fun, and it does offer a lot of depth, but the problem I have with every online card game is cards that give random effects. Karma, even though this champion card is weak, can provide unbelievable RNG that could literally change the state of the game. There is no strategy to RNG, and it provides no responsive effect if a deck that is locked to 2 realms, can have access to other realms spells. EVEN IF it is locked to your decks realms, it provides extended dominance by giving you more cards that go beyond the card limit of your deck.
The major problem I have with RNG cards, is when people say variance is actually strategic. Imagine if items in LoL had RNG effects (beyond crit, which I'm surprised that is still in the game I think? I haven't played LoL in awhile). It'd just kill the gaming experience if a champions ability had a chance of doing extra damage, or if a player was able to purchase an item early cause he was able to snag even more extra gold off a kill. Imagine if ability cooldowns were reduced with a random number. This is BLIND to the opponent, and they have no way of reacting against it until it becomes apparent what that RNG effect provided.
Hearthstone is a great example of why RNG is really bad. It can either make or break your game. Even getting that extra 1 point of damage can HEAVILY sway the game by denying board state, or it can literally just make you lose because it can provide you a card that has no benefit whatsoever.
I hope something like this gets changed later down the line. Obviously some RNG is unavoidable, like drawing. I had fun playing LoR, and I can't till it releases :)
