What other use does the hand's attack option have?
Well ... concidering DnD Tabletop rule for this spell:
You can use the hand to manipulate an object, open an unlocked door or container, stow or retrieve an item from an open container, or pour the contents out of a vial.
+ From Larian ... shove.
In my opinion, that is still pretty usefull spell in combat ...
Ok, let me clarify, What other use does Unarmed Strike have except in combat? That was the implementation from Larian that Kethlar expanded his idea upon. The idea you ridiculed with your sarcastic response. Not what use Mage hand has according to the PHB. Not shove. Unarmored Strike, one of the current options available to the hand during its action phase.
If you think that it shouldn't have Unarmored strike, that's fine. I agree with you. But its there, and you basically told Kethlar he shouldn't use it because that's not what Mage hand is for. You could have just gone with, that, instead of making strike more useful, it could be removed altogether. Which you also did. In your first response. And then, when Kethlar explained his reasoning, you, as usual, had to act like a douche, thinking you were witty.
