I wish more games had voiced banter between the party members to each other during gameplay.
Trails and Xenoblade had those small touches like characters shouting out another person's name when healing them or doing a combo attack with them made it feel like they were on the same team. There were also unique interactions like Jusis and Machias getting mad at the other if they healed each other. "I don't need your help!". Or Machias telling Jusis to shut up during a combo attack. But then you also had the post-battle victory skits with unique character combinations. It would be neat if they did more unique character combo talking like that.
I was impressed by how in Heroes of the Storm and Overwatch, you had a large roster with all of these unique dialogues between characters before the match began, like Azmodan asking about Chen Stormstout's beer, or Genji and Dva challenging each other to an arcade duel after the fight. Overwatch also had unique lines depending on which character killed which character, like Reinhard calling Reaper a traitor, and it even changed depending on other factors like whether the character was low HP, was buffed by a certain character, killed the other character with a certain ability, etc.
It annoys me that these billion+ annual revenue Chinese gacha games with humongous budgets don't even have basic voice interactions between characters that Blizzard and smaller studios did.
