With Oktagon taking the helm we have seen some dramatic improvements to the game and a clear pivot in stance around the conductibility of the cards. I am really excited about the new direction of the game and wanted to take a moment to lay out a case for how the developers could (should) approach card balance. The last thing we want is a few dominant strategies making up the entirety of the meta-game for end game players.
The current state of the game is that the cards have fixed stats and functionality and only extremely overpowered cards end up getting adjusted (nerfed). But why should this be the case going forward? Unlike paper MTG, D3/Oktagon can access card usage statistics and use this information to constantly make small tweaks to the card pool in order to create a continually shifting meta that always encourages new ideas and different deck construction. Consider other successful games like WoW or DOTA. They frequently make tweaks to abilities, stat gains, etc which causes the game to constantly evolve and have a different look and feel.
Rather than engaging in debates over whether Omniscience deserves a nerf the community would have a clear expectation that all cards will be constantly monitored and slightly adjusted in order to have a fresh and challenging game-state. It is one thing for the company to sell Baral and then nerf him as the only nerfed card in 2017. It is a different thing if your expectation is that the card will be similar in design but will be tweaked up or down based on realized strength in the meta-game. You could argue that people might not want to purchase such a fluctuating card, but look at it form the other perspective. Might you have bought Depala, Mirrorwing Dragon, Terretorial Gorger, etc if you knew they would likely get buffed in the future?
Some might see this being a very time consuming task, but I suspect you could use machine learning or even a basic algorithm to make suggested tweaks to the card pool.
Let me know your thoughts!
