Hmm strange; I’ve had kinda the opposite feeling… But I’ve been playing EP since 2018 and only just started PC recently so maybe its a “newness” factor.
Regarding this bit:
You’ll find (I’m like 99.9999999% sure) that the odds on the Training Centre 13 is exactly the same between PC & EP. In EP, its estimated to be about a 5% chance for getting a 4* hero out of TC13. So if you got multiples you got REALLY lucky… I know @DaveCozy ran the TC13 for ~6 months in PC & never got a 4* hero…
It’s worth remembering that both games are a grind… Neither are meant to be “completed” in a sitting… You play, you grind, you progress. Repeat.
You’ll note that the stat distribution is quite different between PC & EP. Even HP is (on average) lower in PC than in EP… Armour is a different factor altogether but I don’t believe it is affecting anything… It’s more like the new “boosted health” mechanic being introduced in EP (note it was in PC first so… )
Can’t help ya with that one Advice is if you’re not enjoying one, ditch it. No point spoiling the other with the failings / feelings towards the other.
