Imagine the following cenários, using RAW:

1)
Bert is fighting Charles. Each of them carry a sword.
1.C1) Charles attacks Bert, but Bert successfully parries the attack.
1.B1) Its Bert's turn and he attacks Charles. As a response, Charles uses Command blocking spell and forces Bert to drop his weapon, loosing his attack.
1.C2) it is now Charles' turn and he has the option to attack or all-out attack Bert.
Whitout his weapon, Bert will have no option but dodge one or two strikes. Then, Bert will need to spend a turn to pick up his weapon.

2)
Bert is fighting Charles. Each of them carry a sword.
2.C1) Charles attacks Bert, but Bert successfully parties the attack.
2.B1) Its Bert's turn and he decides not to attack (maybe perform an evaluate or to do annoter action)
2.C2) it is now Charles' turn. If he wants to make Bert drop his weapon, he will have to spend a full turn casting command spell (loosing the opportunity to attack, suffering the possibility being interrupted and spending his block spell of the turn).
Even if he succeeds, it will now be Bert's turn and he will have the option to pick up his weapon before being attacked by Charles again.

If you consider other Blocking spells (Blink, for instance) it becomes clear that, in some situations, getting attacked could give huge advantages over not being attacked. This becomes even stranger if you consider a 2x1 fight using Blink to maneuver.
