My first point is simply:
Blessed Chest and the remaining Hot Events haven't even been a thing for atleast 2-3weeks now. For about 3-4days things were given for free unknowingly, you genuinely didn't have to open anything and they already had 'Claim' on them(which was glowing red by the way) How do you let these mistakes afflict us, and you as a 'Game Developing' company? It's appalling.
The Tavern:
Who seriously wants to recruit 2 epic heroes? Oh wait, I know! People who want Tomyris so easily. Lets see a player who plays quite regularly wanted to have a strong Rare hero, to obviously increase their BR and replace a Rare hero, due to tomyris being so strong as a rare hero they just easily obtain Vercingetorix(the guy on the left) they just spam this, taadaa get nero and gg, they have tomyris and the devs made a mistake, well done. Vercingetorix is so strong to obtain, on par with Eric Bloodaxe, you recruit them(or him preferably) by spamming Faction Battles, now lets have a look at this, my time that's 2:30, yes my mistake I was put on a US East Server, I am 5 hours ahead of you, but that's irrelevent, the players in general know that Faction Battles are not FREQUENT enough, allow me to emphasize that FREQUENT, they are once a day for 30minutes, barely any players even play it anymore(probably due to their infrequency) and I obtain about 40-50honor per faction battle, doesn't mean all players obtain that much, I gain quite a fair amount, some players earn max 60-70 honor. It takes 240honor to recruit one emblem, you need 5 emblems to recruit him. Do you understand the grind that would have to take in place? No, because you're completely unrational and have no idea what you're doing as a team.
Add super rare heroes and rare heroes back to the tavern.
Guardians - Same, everyday literally no alterations, disgusting.
Back to the Hot Events point.
There would be a list here, now there's basically nothing.
