Is that what it is? I was under the impression that it was originally a scrapped hero and Bera became the end result of what Salmon Loki was going to be. And that “non-negotiable” bit was a little play on the Q&A with devs when they talked about limit breaker and costumes for non-s1 heroes.
But I guess to a certain extent, it’s probably because they already spent some time and resources on it, and SGG rarely leave anything unused… So in that sense, it’s probably still “non-negotiable” that they were going to release the Fishy Loki.
Well, I am finding uses for HA besides level 10. I’ve always stored Recruits and Food into my TC20s, but with the Hero Academy, you can actually use it to train Troops 1* - 3* (HA2, HA4, and HA6), which is pretty much the only guaranteed way to get troops besides summoning out of the troop portal, get them as random loots off of maps or silver tokens. With Iron being used comparatively less after finishing the building upgrades vs. food, I have found myself parking my recruits and excess iron into HA6 to train 3* troops, every few days gets you one to boost your troops leveling grind. Plus with HA, although not as optimal as the Alchemy Lab, you get to do 2 actions at once. So while I drop my dupe 5* vanilla in on HA10 weekly, my other concurrent action is HA6 with 3* troops.
