Ok up until someone pointed out that the change never applied no one said a word about this unit, the moment u found out , it’s a problem? If this is not confirmation bias I don’t know what it is
This has been brought up in the past, but since there are more pressing issues, they are just put back in the "To do" list.
Same with Rangers. Once they found themselves been part of a rework, they were changed.
Now comes a matter of philosophy: do you fix something which is wrong even though the unit is fine/bad? T3476 had a ninja applied RoF buff and they were still crap. A patch fix the situation making it more worthless till they actually buff the unit to it's current state.
Damage modifiers, specially passive, are always gonna be strong. It's more a matter of them been on the right meta or common commanders whether you will see them more often than not.
