I don’t think the argument is “you can’t get stuff playing treasure hunt”. If I grind anything for a year, I’m going to have a ton of resources laying around.
The argument is, “treasure hunt rewards per unit time are paltry compared to other modes”. I do think you have a very good point in that RNG has a lot to do with how treasure map stacks up. I think it’s possible it’s the “best” way to farm glory.
I think some of the frustration also comes from treasure hunt not being a mode you can “progress” at like others. For example, if I feel like I’m losing PvP too much, I can tweak my team and try other troops. If I don’t feel like I’m getting enough treasure hunt turns, all I can do is have people on the forums tell me “be more careful” and “take more time”.
I dunno. I like that treasure hunt’s this weird thing that plays completely differently from everything else. I’d like it if I felt like I got rewards comparable to what I get from playing Explore matches, but then I think the people who are super good at treasure maps would get ridiculous amounts. I play it every now and then, but only average about 60 turns so I don’t think I’m ‘good enough’ to see how the rewards stack up.
