Let's say I move through a threatened square and provoke an opportunity attack. The monster I provoke from has an ability that dazes me (save ends) on an OA.
Or, I ready an ability that dazes (save ends) to interrupt a monster's movement.
I see the following ways to handle the situation:
1. The target is immediately dazed and ends it's turn since it has already used at least one action to move.
Drawbacks: If the target has already used it's Standard and Minor actions before moving, and saves at the end of it's turn, the daze has effectively done nothing at all.
2. The daze does not take effect until the end of the target's turn. Therefore it does not get a save until the end of it's next turn, but can continue to take a Standard and Minor action on the turn it was dazed if it hasn't done so already.
The first one makes sense to me, and is probably correct, but my party has a house rule of thumb that any power that imposes a condition on it's target must affect the target for at least one round. This also makes sense to me, as it seems unfair that a simple mechanic (provoking the OA/readied action once your other actions are exhausted for the round) can effectively nullify the use of a potentially expensive (daily or encounter) power.
My party uses #2 since it adheres to our house rule. However, it doesn't really make sense. An enemy can daze you then you can still take two more actions.
Is there a more elegant solution (official or house rule) that doesn't make the daze completely ineffective while still making logical sense?
