Thats it, I'm never going to trust a mage again in this realm (LOL). Mages have always had a very bad reputation since the first Dragon Age, but now i've been duped twice by mages who put on the facade of fighting for a positive message for mages but having an ulterior motive. I took a break from the game only to come back and finish it. First Anders and now Solas? WTF? The worst part is that Solas is and elf and a mage (thats  twice the discrimination). I don't understand why the mage always has to be the unstable villian and for those reasons from now on in the next Dragon Age I will be more weary. 

Also, he took out flemeth really quickly. Ever since the first Dragon Age she was one of the most feared beings in the wilds. At the end we find out shes not as bad as she made herself seem causing confusion even with Morrigan as to her identity, personal relationship and motives. From that point shes taken out by Solas? Freaking Solas!? This guy has been masking his power since day one. If he killed Flemeth this guy is insanely powerful.

I mean, every group has their problems but the mages have to be the most unstable and power hungry group. They can never agree with certain sects and even when you fix things there is still a problem. I helped the wardens and they rebuilt themselves. I made Cassandra made a divine so the the mages could be governed properly, but no....the circle had to partially rebel and create a rival college. Its like no matter how hard you try to help them the situation splinters off into a worse situation. I don't even want to know how bad the Solas situation is going to be in the next game if he was able to kill Flemeth. 

You realise Solas isn't just a mage or an elf?

He's something far more powerful. He's effectively an elven god.

This

And furthermore he is not necessarily evil. Also the ending is entirely ambiguous, considering Flemeth dead is a bit of a reach.

I am convinced Flemeth took Solas. Remember all of that banter between her and Morrigan about how she could only take a willing host? Solas looked pretty willing. Dire Wolf+Flemeth = super boss

I understand, but thats why I am so surprised at how much power he hid from everyone. He played the role of a cub when in truth he was a freaking lion. I am just saying that even though he turned out to be more than a mage he posed as one no different than Anders in the last game who went rogue (to my recollection he allowed himself to be a vessel of a god as well). Next game I am going to be very, very cautious of mages all the way from Tevinter to the newly established college. The only mages I might give the benefit of the doubt to are circle mages and even then i will still be on my toes about how I deal with them.

There might be something to this, but I don't know. I am reading other peoples statements and they are saying the god in flemeths body is now in posession of the body of Solas.

Yeah, a god had taken Flemeths body as a host. I remember that. She probably just let go of the body of Flemeth and took the body of Solas. What an interesting setup for the next game. Has me on edge. I was so pissed but also so eager for the next game.

If that is the case then that makes flemeth anything but dead considering her and Mythal had really become one the way I understood it. Though I imagine we'll be seeing some more of the old god personality emerge now that there's at least 2 god souls in the mix

Let's not forget that according to the DA lore "Flemeth" has been around for ages, in this time there's no telling how many bodies Mythal/Flemeth have actually gone through and yet all throughout she has maintained the identity of Flemeth, so just because she's now in the body of Solas doesn't mean that's necessarily gonna change

The difference is that Anders went mad due to the circumstances in Kirkwall. He never hid how he felt and I didn't think it was a big shock when he did what he did (maybe the scale).

Solas was never mad. He always had an ulterior motive and to be honest, I don't think it was neccessarily all bad. There are actually a lot of hints to Solas being far more than he lets on. He's always quite distant, always seems to be sad or regretting something in the past that he keeps well hidden and if you put him in your party with Cole, you often get a lot of hints that there is something major in Solas' past.

Whilst he's hidden a lot from the player, I don't think that it's for nefarious purposes. Spoiler/theory alert:

If you read up on the lore it's apparent that the Dread Wolf/Solas sealed the other elven gods away, with the exception of Mythal/Flemeth. This then lead to a weakened elven race which was ripe for Tevinter to come in and enslave them. This in turn has lead to the current state of elves being perceived as second class citizens and forced into alienages. I think Solas/Dread Wolf sealed the other gods away for good reason. The elves were warring with each other at this point (at least from what I can remember). But his actions had unforseen circumstances that he's now trying to put right.

Strangely, the lore also states that the Dread Wolf betrayed Mythal, yet in the ending they seem to be old friends. Earlier in the game, Flemeth also states to Morrigan that spirit/body transfer can only occur when both parties are willing participants, so the question remains, what has happened between Solas and Flemeth?

Either way, I think it's a great twist and the general story/lore of Dragon Age has really been expanded upon since the generic fantasy storyline depicted in Origins. I can't wait to see how this will be expanded upon.
