TVs will be hard to bring back considering the whole point of 2.0 was to ensure the heroes will never need to use TVs again.
But the problem with TVs isn't as simple "it was bad and we took out so there is nothing to complain about". I don't think people are missing TVs as much as the original premise and having
something unique to do beyond fighting, cause when all you do is fight, you have nothing to distract your from how everything else in ZZZ is mediocre to bad.
Devs must have thought "casuals like open world, make it open world" but it's not really open world and the game was built for small arenas so now you have bad fake bad exploration and the game runs bad.
A good story could save it but it does not have a good story because they're making shit along the way and improvising. It has to introduce two new 5* every patch and give them the spotlight meaning you get nonsensical "monster of the week" villain and is no time to build hype and they disappear after that patch.
The combat is good sure but they broke the emergency glass so hard with Miyabi that it's balance inspires no confidence and keeps getting worse. I heard they keep buffing anomaly resist in endgame to counter miyabi but it's never enough and it can't be enough because they have to balance the game around her being the best now.
So instead they make up new mechanics that only new characters can counter (miasma?) and new supports that buff those characters but not miyabi, except hoyo players are too savvy by this point and know the new shill will only last 1-2 patches. Why roll a dps that isn't void hunter or "void hunter level"? How to trust this support won't be powercrept after 6 months? Will this unit will counter this boss for one patch and be useless after it? Why bother?
Then you have tweets like this lol
(apparently the new stunner Dialyn powercreeps every previous one and can replace them in their niche)
Not that genshin and HSR don't have creativity and balancing woes (i fucking hate lunar reactions what a waste of space) but they have other things worth caring beyond unit power levels. Hell there are probably people who only play miliastra and don't touch genshin at all.
The world was interesting but they gave up and now it's CHINA and wuxia and there is magic and they must assume the players don't give a fuck and only want reasons to goon. Shut up about mecha, here is a foot waifu, you must goon and consume. Lets bring the idol lolis that leaked, everyone likes lolis and idols right? The women are leaving, send the husbando bait but make sure they're doomed or it might offend china.
ZZZ lack of planning and gacha greeds combined with it's failed attempts to pander only serve to alienate it's own players over and over.
