Giving a disadvantage is all good. Obviously you need to stretch the rules a bit (basically saying that 2 air opportunities can create a disadvantage, which IS legit). Now, how long that disadvantage last etc ?it becomes another argument at the table. Probably a 1 turn should be fair.
Better than center and predict nontheless...
In the case of aramoro, wasn't it like a poisened blade? And not a "temporary disadvantage"? I dont recall exactly.
Edit; "temporary situational disadvantage" is something that should come up more often, like Blue dice in starwars/genesys.
Sometimes an increase of TN is too rough, but a disadvantage (like in the case of the sun in your eye with a 2opp air use, or maybe when attacking while prone) is something that can polish the rolls a bit without unbalancing too much).
