Storm Banner and Miscast

Rules question, vis-a-vis, the Skaven Storm Banner and miscasts...

The following issue came up at the tournament:

Skaven player has the Storm Banner in play. Rolls a miscast and then an 8 on the miscast table...miscast 8 has a provision that all spells in play come to an end...

Question: Does the Storm Banner stop working (not necessarily burn out, but stop working) because of the miscast?
Ruling at the tournament: No. Reason: The Storm Banner is activated outside the magic phase and is not a spell. The miscast states that all SPELLS that are in play are ended, not magic effects from magic banners.

Called GW today and got "Sanchez" (already had issues with some of his rulings, so will call another day in the hopes of getting someone else and seeing if he agrees).

His answer: Results on the Miscast table will have NO/NO effect on magic banners, unless the effect specifically states that it does. So, in the case above, the ruling was correct (at least for the moment).

Of course the ruling is correct! (in my opinion) because of the reasons stated above. I personally don't see how that miscast could affect the banner as it's not a spell but a banner

I don't see what the issue is here.

At no point in the wording does it say "all magic whatsoever on the battlefield ceases to exist" . If this was the case, magic weapons and armour would become mundane and other magic items would cease to work. This is not the case. All that happens is that all the current spells in play are immediately dispelled, and all power and dispel dice stored in magic items are lost also, and the magic phase ends. Thats it.

The Storm Banner is not a spell. Unlike other Banners that hold bound spells, the storm banner simply goes off at the users command. It cannot be dispelled. Therefore, an 8 on the miscast table does nothing to it, because it cannot be dispelled.

I ultimately came to that conclusion, but wanted to be thorough.

That's exactly my point.

Done and done. And now to properly shoot that rat in the first turn!
