I don't think that different symbols actually being the same symbol makes the most sense. To me, different symbols actually being different symbols makes the most sense.

Official rule, not ruling, actually.

That's why the judge should be making sure that his players are aware of the deviation. If he isn't, he is doing a pretty big disservice to his players.
Quoted for truth.

Makes the "most sense" doesn't change the "house rule and should be noted as such" aspect of things.

I start arguments even when I'm not trying to do so!

A.) Yes, everyone at the venue is aware that it's a house rule.

B.) We haven't ruled similarly on any other TA like this because it hasn't come up before now.

C.) I can't say definitively (I wasn't there, either), but it seems to me that the movie symbol was different purely for reasons of appearance. It's odd that the Batman movie sets are the only movie figures with "variant" Team Symbols.

D.) I wasn't trying to petition a rule change or start a debate. My OP clearly shows that I knew our ruling deviated from official rules.

E.) DO the different Batman Enemy TAs work together?

BATMAN ENEMY
Characters using the Batman Enemy team ability may replace their attack value with the unmodified attack value of an adjacent friendly character using the Batman Enemy team ability.

All that this requires is that both characters can use the TA. The symbol is not a component of the TA's function. Otherwise, it wouldn't work for wild cards, either.

See? This is why I like the Rules Deputies. I learned something!

Official rule is actually for WizKids sponsored events and all those venues (like mine) where we actually follow the standard rules. You're free to have the house rule that makes you and your players happy, but assuming that's what everyone else is doing is erroneous.

I question if the card for the cowl had been made years ago before a symbol was used for a lot of things, would they have just written out "batman ally team ability symbol" like it appears on the units section here. That covers both symbols. It seems the symbol is used to shorten sentences, not exclude DKR figures.

They've differentiated between possessing a team symbol and a team ability before. Not sure how this would be different.

That is not accurate. Look at Batgirl from the Batman set:

Reborn as Oracle: Batgirl possesses Earthbound/Neutralized and the Justice League Team Ability.

She can use the Team Ability rather then Game Design stating she has the symbol. This was made in the same set the vehicles were made I that use symbols for prerequisites.

I'm pretty confident that the rules team verified some time back that Game Design wants it this way. You may not feel it should be that way, you may doubt the wisdom or reasoning for using two different symbols.
Both, after all, are really matters of opinion and personal preference. But I don't see any reasonable doubt that it works the way it's supposed to work.

Well this is terrible news.
Marquee batman has no defense against the Justice League now.
This makes him... unacceptable.

He still has his Fists...

but but but, those only work if he doesn't get orbit striked by them in his starting area.
