Since the player character doesn't speak outside dialog trees, which is unfortunately rare, I dont mind. Archeage forced voice acting on the player breaking any and all immersion. But whenever "you" talk it's usually just mouth flaps and waving your hands, I tend to fill in the blanks with my head.

"Man that fight was dope yo, broke his goddamn wings off and I think Alphinaud wants to be my wife."
"Pray, Warrior of light. Rest and mayhap have succor from your arduous battle." (dramatization)
"Ayyy later fam."

Besides, it really works for Lominsa, Ishgard and Gridania. If anywhere that I'd find it out of place is Ul'dah. Just seems the most modern.
