Thoughts on this vault.
6K hero points you get an Ascended 3->4 Deadpool at 270. That's essentially 126 covers of 3* Deadpool (13+100 to get to 266 + 13 more to baby champ another Deadpool) plus the ISO needed to champ 2 3's etc. Of course you don't get the 3 star champ rewards but it seems to me its a huge time saver if you've already ascended an existing 3 star Deadpool (as I did) so that you now have the 2nd 4 star Deadpool you need to ascend to 5 star once you get 200ish covers (mines at 288 so I would need 82x3 240 more covers to be able to ascend him) to max champ him as a 4.
You also get some shards of the 5 star Ghostpool and other assorted goodies. But the real value to me seems to be the savings of 126 covers + ISO.

Yes, that was my take.
Fully ascending DP seems worth doing and this knocks loads of time off that process.
