It never felt like an auto-win to me because sometimes it was more advantageous to just duke it out. (Or in the case of a certain cookie-loving Templar, funnier to let your companions convince him) Conversation just seems rather limited in DA:I as there's no situations I've encountered where you can talk your way out of a fight (or talk your way into one, for that matter). Everyone either attacks you on-sight, or occaisionally talks to you first and then attacks you, regardless of you actually say. Besides that, the fact that you can never try to BS or intimidate people just bothers me.
While the various Lore options are nice, they're based on knowledge rather than your character's ability to be convincing.
Survival (on your Warden specifically) was needed for the sick halla quest, though I admit there wasn't much other use for any of the other skills if you weren't playing a Rogue.
Ideally, it would be nice to have the skills brought back in general, but modified with each having a purpose for your character to take them, so it really is a trade off. Persuasion makes you better at talking to people (and if you do manage to solve a situation non-violently you still get XP for it) while maybe Survival gives you combat bonuses against "natural" creatures and the ability to spot hidden areas in the wilderness or maybe increases hide drops from creatures killed to reflect your ability to skin them more efficiently. Herbalism not only lets you makes potions, but increases the yield of any plants you harvest and the possibilty of finding seeds. Etc, etc. Give us several skills to choose from along those lines to customize our character to our preferred play-style.
