So,
I did some testing of switch/trick today. Tested on a full buffed character.
Out of 30 "Switches" 4 were successful (13,3% chance)
and
Out of 30 "Tricks" only 1 was successful (3,3% chance)
Then i tested it on a character without buffs, it was significally better but that's irrelevant because last time i checked noone goes out without buffs
So it means that you can't rely on these important skills and it's lost time during fight if you use it. The chance should be atleast 33% or more to make it a little useful.
Check it please once more
