Collected my 4th set of 10 Souls yesterday evening, together with the 11 I got from the rewards it made 51 out of which I got 1 Blue pyro soldier and 1 Ace's Bomber. So I ended up with 2 Ace's Bomber. Other than that the only notable char I got is the Gunner Iron Maiden Eddie.
In terms or resources: it cost me a bit more than 1100 Ironite and a lot of time.
I still did a few more runs to get the legendary Heroic soul, just in case. I won't do the extra effort to get the Feldmareshal though, I'm already close to the 2000 runs and I'm fed up. It would have never been possible without the autorun. I went 2x to bed with 1200 SoT and collected the rewards in the morning... but didn't sleep well, was too worried it would crash during day reset which happens on 1AM CET.
One improvement would be to have the possibility to let the app run in the background like fitness apps Strava and Runtastic, that way I could still use my phone, for other things. If that was available I would have gone for the Feld.
In terms of additional rewards 2000 runs in Hard mode, I cannot complain:
- About 18M Gold
- About 600 FC
- About 20 Crystal Shards
- 10 primordial talis
- a lot of colorless shards
- 650 SoW (which is ridiculous since I don't have good toons to play well in PvP)
