[4e] Helping Someone Else Stand up

[Kurald Galain]

So, what's you opinion on spending a Standard action to give someone else a Saving Throw. Or +2 on a Check?

That the former is generally a waste of time, and the latter is always a waste of time.

I mean, how useful is knocking someone over if their adjacent ally can just blow a Move Action they weren't using anyways and then attack?

(1) That it's not a given that there is an adjacent ally, (2) that it's not a given either that said ally wouldn't be using his move action, and (3) that you're still getting combat advantage in the meantime.

Prone is not a very strong debuff, nor is it intended to be a strong debuff.
