>>55280130>Is it too lateIn terms of gameplay power creep? Not at all. The re-occuring game modes difficulty is player-determined (higher scores, longer streakers, picking tougher E4 buffs, etc.). Stronger characters mostly just let you push harder for a few extra goodies.
Character acquisition-wise... yeah it will be rougher going at this point. You get enough free money to nearly guarantee two characters from all of the story stuff, and every 6~ weeks from doing all the events. Meanwhile they put out 4+ new ones a month along with re-runs. You slowly hoard to get what you want, you can often go favorites over meta because of point number one.
The crux of it really is if you end up liking the game enough to find that wait acceptable, and you'll see most of what the game has to offer in three months or so.
>Can I play my favsNot exclusively. Some one-time battles are explicitly built for certain regions or types or characters to be used, the re-occuring game modes all require multiple teams, and sometimes their battle roles don't compliment each other. Default Misty, Rosa, and Skyla are all supports, for example.
