(seriously, she is probably the most educated character in the series; she can recite the entirety of known elven history)
is right about eluvians
is unaware of human cultures bc she’s most likely never met a human before Duncan, and even him she knew for like five minutes so it’s understandable
bad with people bc she was isolated as a child (it’s implied that Mahariel and Tamlen were basically her only friends)
according to Solas at least, she’s right about blood magic being only as evil as the purposes they’re used for
is very proud, that’s true. she’s arrogant at times, but it’s not like she’s the only character in the series with that trait
is perfectly willing to accept the consequences of her own actions, but due to low self esteem and self-worth she doesn’t understand that other people would be affected by them
is incredibly gifted magically; she mends a corrupted, shattered Eluvian, rebuilding it and cleansing it.
this potentially means that Merrill will be able to apply her study of the mirror to curing the Blight
