Things from TCGO that I miss
Firstly, there's a severe lack of character customization. I can't have an afro, I can't have beard or any facial hair at all; TCGO had those options so it seems like a big step backwards. Secondly, the lack of any single player vs mode to help balance sets or just have a little fun; I really liked the trainer challenges of TCGO so seeing them just disappear is depressing. Lastly, seeing all of my decks, even official ones, just disappear from my deck list is pretty silly. The cards are all still there but I don't want to pull up a list to rebuild them from scratch.
I will say I enjoy the graphics in a general sense; the new visual flair for attacks looks pretty great. The 3D characters look alright, even if they are lacking customization options TCGO had like the facial hair mentioned earlier, but they do look nice for what they are.
Overall I'm hoping to see these kinds of features added to the game eventually, because frankly, I won't play it much in its current state. I know it's early and obviously will get better with time and more content, but overall it seems like a big step back comparatively.
