Yeah, the tabletop text is pretty friggin' clear.
As it is, the gift becomes much more effective in MET than it is in TT - you reduce die pools by one die per two successes on your roll, which means you're likely to remove at two dice (if you roll particularly well) from someone's efforts for one in-game day, which in a tabletop game may be one scene due to fast-forwarding, or the character deciding to take a day off - in larp, it's nearly guaranteed all session.
The spending-traits-as-successes mechanic means that the likelihood of only hosing them a little bit is gone, and you can now hose them more or less as much as you choose to. This is bad enough when it's something like the basic Galliard gift Distractions, which lasts for a round. Making the intermediate gift go from one round (for the same cost, plus a Gnosis) to an entire session of play is also pretty hosing. Asking for it to do all that plus go for multiple days is... excessive.
