I made an account just to write my opinion on the matter.
Personally, I'm one of those people that switch between FP and TP as the situation demands. Since Bloodlines 2 is an RPG with an "extensive" character customization (and this apparently includes a whole wardrobe of outfits that we can use to express ourselves; I think one of the devs mentioned this at some point as part of our prologue experience) it makes sense to include a third-person perspective. As a casual RPer who spends too much time fine-tuning her character's appearance when given the chance, I too like to take a break sometimes and oogle my character from head to toe.
Now, I can understand why some people are so vehement against it; they are worried that adding a TPP is going to take away time, money and resources that, in their opinion, are better off being spent in other, more critical, parts of the game (i.e, story, quests, etc). And I partially agree with them there - a third-person perspective implies adding a whole list of animations; walking, running, grappling, bitting, climbing, hair, body and clothing physics, etc. Third person melee combat can be very complex, especially if you're going for quality, smooth and believable moves with weapons in mix. I'm imagining hiring two actors (one male and one female) to help with the motion capture and then working all the kinks to make it into proper animations mustn't be cheap.
Assuming this is indeed the case (lack of money, time and/or resources) one must ask which is more costly in the long term - implementing full animations for third person or losing a portion of the community that can't or won't play without TP. I honestly don't know which is worse. My bottom line is: I'm alright with giving players what they want, provided the original product doesn't lose quality over it. I don't intend this to be a jab at people with disabilities, I actually kind of feel for you. Gaming is my passion and if one of my favourite titles, who took over a decade to get a proper sequel, came out and I couldn't play it due to health reasons... I'd be extremely disappointed and sad.
But if implementing the third person means the game will lose some of its potential quality (which may or may not), then I'd rather not have TPP. I'm sorry for the selfishness... but it is my opinion.
PS: Don't forget that modding is a possibility as well, so even if the developers can't do it, there's a chance the modding community will get a way around it.
