Unless I see anything noteworthy content-wise, I think I'm finally over this game.
Opened up the game, grabbed my pointless daily reward of a dueling crest to add to the pile of the other 55 I have because the arena is an unfun slog. Figured I should at least try to improve my arena score for this week so i load in, select the first advanced team I see with an Olivia as the leader and it's a horse emblem team with Reinhardt, Cecilia and Xander hidden behind Olivia as a leader on that goddamn boat map (see post above). I just closed the app because this is just becoming tedious.
I can understand if they can't decrease the strength of x emblem team setups due to that case around decreasing the strength of units in gacha games, or maybe they don't even want to because it provides an easy way for everyone to become competitive and they can make quests such as the 'kill x enemies with a team of cavalry units', but they could at least give us something like an anti-cavalry/armor/flier sacred seal at this point to help mitigate this complete bullshit.
Having units with an effective range of 7 spaces on maps this small that also have a way to become incredibly overpowered through group buffs in a mode where you can't see what you're actually fighting before you enter the battle and are encouraged to lose as few units as possible is absolutely terrible.
I'd care less about arena balance if they could actually push out meaningful PvE single-player content, but we get a few new chapters every time a major new hero is added, a GHB every now and then - though they've started recycling those now - and that's really it. The rest is quests and grinding outside of the arena.
