All-out attack presents an interesting strategy, being able to double the damage of most attacks. Unfortunately, that also makes it difficult to balance, and it does need changes, in my opinion. The big one is multiple all-out attacks. The way the game is programmed, it makes logical sense that every all-out attack activates as soon as possible, so if an attacker has multiple, multiple are used. But this presents a huge balance issue as it causes characters to be one-shot. Now, some of you are probably wondering: "what's wrong with having a one-shot?" Everyone that has played PvP knows consciously or unconsciously that all characters are supposed to take multiple attacks to kill. This is important because in between each attack a player makes, the opponent gets an action to respond. This is an absolutely crucial element to the game. You are only supposed to lose when the opponent corners you, outwits you, removes all of your options, etc. It's a process that takes a bit of time and happens over many turns. Simply put, whittling down your opponent is the core of the PvP gameplay. I don't know the design goals of the dev team, but for the players, this should be very clear. Being able to kill the opponent in a single hit directly contradicts the spirit of the game, as the opponent has no chance to respond. They're basically killed before they've played the game. The game is simply not designed for spike rushes. I think the following one or more of the following nerfs should be applied to AOA. 1. First and foremost, only one AOA should be able to be used per attack. 2. AOA could auto-reveal. This allows players to play around it, since it has such a huge advantage. 3. AOA could negate all positive and negative damage modifiers on the attacker and the defender. No more frenzy boosted AOA, but it would also bypass armor and would ignore penalties such as wimpy. 4. AOA could only work if the target has no attack cards in their hand. 5. Perhaps a reduced multiplier? Maybe a static one. Honestly, what does AOA add to the game? Not much, in my opinion. All it 'adds' is an extremely annoying mechanic that contradicts the spirit of the game.
