gashi, no, that's wrong, stop
Pictochat's transformations ARE indeed random, whith random durations and random "blank" times.
I didn't say Pictochat were banned because of characters. There are actually few characters good on it, like Snake, DDD and Sonic.
The reason ig got banned is that people got the idea it is janky because they don't know how to play on it.
Just doing your normal stuff doesn't work there. Rushing to your opponent while the stage is blank is asking for something "janky" to happen. The *ideal* gameplay there would be to play very carefully during the blank transformation (lowering the amount of care as the most dangerous transformations pass) and start moving when the transformation is out.
Annoying, probably. Effective, indeed.
But people took the easy way out, and instead of learning the stage, they simply banned it.
