What I don't particularly like is full VO. Not that it annoys me or something - but It's unneccessary for me and it's so freakingly expensive that I would rather see that money and time invested elsewhere. Fairly unpopular opinion I guess.

Well, usually with full V.O. you usually have less options in dialogue and shorter and fewer dialogues, because it´s expensive and also it´s a hell to mod story content in the game, because most think it´s a little lame if the rest of the game is dubbed. It was ok in games like KOTOR because most aliens talked in alien gibberish so you can use that voice to whatever you write, but it´s the exception.
That said, studios with deep pockets like bethesda or obsidian made a great job at dubbing (In FO4 they even dubbed the dialogues of the robot butler with a hundred names, like jack or Maria so he speaks to you with your characters´ name) but usually is not the norm.
Generally speaking, I prefer the games not fully dubbed, not because of the dubbing, but because of the consequences in the dialogue.
Team initiative, while not standard 5e, will do a lot to speed up combat. One of the downsides of DOS:2 multiplayer was waiting for your teammates to go, then the enemy, then you...etc. All players being able to move and act at the same time will help the pacing imo.
Well, in a game of D&D you also have to wait for your turn, so it´s not a big deal to me. I think it would be more chaotic if all the players move at the same time, like casting a fireball at the same time you are charging the enemies, some party members got hurt due to reacions or environmental effects and the cleric/bard already casted this turn so he/she cannot heal, etc... The trick would be to play with discord , teamspeak or mumble to talk to the others while playing so we can plan the moves, I supposse. If you do not have experience as a group or some teamwork expertise in the end the turns could be even larger than in the standard initiative mode.
