I tend to agree, I have learned to expect an average (it’s actually about twice that, in practice -for me at least, but you know, small data sets and all aren’t proof, and this one has some pretty wild swings dependent on wether or not you pull full characters) of 1 shard per 1,000 ally points spent, and even that nets you 750 shard store currency per 50k spent (along with a lot of that nagging low end white and green gear that even us 4 year players have to go back and spend energy on once in a while), which is still 4 purchases of 6 stun gun salvage at 186 currency each.
That said, I happily spent 50k Ally points on 2 Omega mats this week (I’m not even ‘starved’ for omega mats at this point in the game, but as a completionist, I still have just over 150 omega abilities, plus more than 80 zeta abilities to go), because you can’t get those out of bronziums or the shard store...
Just like most other resources in the game, (I hate the term ‘hoarding’), banking a small stockpile of will give you the flexibility to do both as required.
Rare item in weekly shipments? Snap it up.
Running low on shard store currency and not an Assault Battle in site in the events? Spend 10-12 minutes burning through 50k ally points worth of bronzium pulls.
