AHEM Welcome to a uh- Uranprojekt level discussion. Let's take a moment to meditate and relax before we begin the discussion. Are we a bit calmer? Good, now from the top!
Aggro has been a deck choice that's meant to be a speedcheck for late game decks/a option for newer players to get into the game. It's been around for a long time and used to be pretty mid, but recent updates have made aggro into a monster. Ever since the Winter War update aggro has been on the upward popularity use trend, where tournaments now consistently have aggro decks in the top three decks used if not all three. It's become somewhat unmanageable and something should be done to help bring the game back from a playground slap fight to a strategic card game.
Firstly, let's address the concern of new players. The battle ready decks (the decks from both nation leveling and store purchases) are specifically made to help new players have something other than aggro decks to use. However, these decks have many issues one of them is that if you lack the cards that are within the deck you cannot use it. My recommendation is to give the cards within those decks to the players for free when they unlock those decks. This will encourage people to not only experiment, but also try other nations so they can unlock their cards too. This helps resolve this issue of new players not having alternative options. The game does have a learning curve, but the ceiling shouldn't be lowered so the floor can be raised. Let new players learn how to play the game and let them make some mistakes/struggle a bit. There has to be a balance between difficulty and easiness.
