I like Merril, but I'm sick and tired of her "suporters" proclaming her an expert on Eluvians, while clamining that no one else (including Mertharari) knows anything.
Did it ever occured to anyone that maybe she knew more than she claimed?
By her own admission, Marethari knew relatively nothing about them in the Dalish Origin, and she doesn't think any research should be done on them in Dragon Age II. In contrast, Merrill extrapolated information from the shard and studied the lore on the Eluvian.
Clearly, Merrill put effort into understanding the Eluvians, while the Keeper gives absolutely no indication that she knows anything about them. Marethari makes it clear she doesn't think any study should be done on the Eluvians because the Keeper thinks their ancestors wanted them buried and forgotten, despite the fact that the Imperium managed to get a hold of them because the Arlathan elves were still using them before the fall of Arlathan.
You might be sick and tired of people pointing out the simple fact that Merrill put a lot of effort into understanding as much as she could about the Eluvians, but I'm not seeing why Merrill's painstaking research and study into the elven artifacts should be dismissed or diminished.
Merrill also stands out as a prime example of an independent mage who uses blood magic but isn't evil, which was a nice contrast to the multitude of criminally insane (and mindbogglingly stupid) mages who littered the narrative of Dragon Age II as hack and slash targets. I'm hoping for more three-dimensional mages and blood mages in Inquisition, who don't wear black hats and aren't one-dimensional evil villains.
