I'm guessing this isn't the case if you're running with friends or guildmates or the like, but from what I've experienced, almost every pick-up Tortodrone run devolves into some level of drama over the crafting of and/or payment for the ID card, or at the very very least involves everyone standing around awkwardly for 5 minutes trying to figure out who's doing what. Obviously it's a function of requiring only one unlocking item that only one party member is going to be using, and then you're forced to rely on the goodwill of strangers to figure out a fair way to split things up, or that they'll even pay at all. My two most recent attempts are a case in point: in the first, I stated that I'd be willing to provide the card if people would chip in some crowns, but after I said that I already had it made, the other party member never offered to, so I just said screw it and started the run. (Said person proceeded to invite along a friend who'd never done it before and had no Sparks...so they spent the entire fight dead. I haven't been that angry at the game in a long time.) Another time, when I was more firm about people chipping in before crafting it, the other group members waffled, offering to take me on another run later (which I didn't have time for anyway) and claiming that they didn't have all of 2,500 CR. You know, less than you'd make from a single T1 Arcade run. Needless to say I'd learned my lesson and just bailed.
How to solve this issue? Simple: cut the ID costs by 75%, and make everyone in the party be required to have one before the gate will unlock. Heck, you can even leave the material amounts the same and just cut the CR cost; it's not like they're hard to come by. If everyone needs their own, then we wouldn't have all of this nonsense.
(In theory I guess this problem could come up in a Shadow Lair run too, and I'd assume that's where OOO got the gate-locking behavior from, but the big difference there is that you don't really do those as random pick-up runs, so everyone will presumably work out the cost issue well in advance.)
