I thought I'd post some Tekken 7 resources I found useful. When picking up a new character, I like to check out here (https://drunkardshade.com/2017/05/27/tekken-7-top-15-moves-for-all-characters/), helps narrow down whats good and usually what you'll be using in the neutral game. After that I'll usually pick up a combo from the training mode move list to help with damage during opponent whiffs (when they miss a move).
Another useful resource is (http://rbnorway.org/t7-frame-data/), here's all the data for your characters moves, how long it takes to startup, how long to recover after block etc. Understanding what frame data is and why its important can be pretty hard to understand at first and this video really helped me understand that. (Understanding Frame Data (Frame Traps, Meaties) | 5 Minute Fundamentals - youtube).
If you have any useful resources to help get better, feel free to share!
