I think the reception has generally been good (I remember the... shirtstorms when DA2 and ME3 were released. There are always naysayers and drama queens, but this release has been sweet as pie by comparison).
That's probably product of low expectations, tbh. That and that the most controversial part of ME3 got leaked days early and DA2 was basically a giant argy bargy all through development and there was no reason at all release would change that (I thought ME3 was great and the ending okay - I took a "it's the journey, not the destination" approach to it - and DA2 was painfully average and not at all up to snuff in many ways, so that could be affecting how I remember their releases).
But yes. Honestly the vast majority of complaints seem to be coming from one specific slice of the user base - PC players - and mostly seem to be mechanics issues, rather than perceived inherent problems in the design (which DA2 had a litany of, imo). Which sucks, but is both manageable for now and fixable later.
