Go Marksman. That's what I did and it plays almost just like pre-Legion survival did.
It's two different approaches, but as a roleplayer, I do find WoW more approachable for that. The "zone story" approach makes it just a little more sandbox than XIV feels. Plus I've liked the zone stories. With FFXIV having such a tightly woven main story, I've not found my imagination wandering to other tales to be told in the other corners of the world (despite a LOT of history and lore to dig into).
Hm, but most of the voices aren't faction based, they're NPCs for quest areas that are unrelated to Horde. Dunno what to tell you if you think the VAing is attrocious in WoW.
If you think FFXIV has anything that can hold a candle to Darkwing Duck himself, I say you're insane.
(Okay, I'm teasing a little, don't take it too personal)
Kind of sad in all the replies, nobody picked up discussion on the music differences between WoW and XIV. You guys disappoint me!
