Side missions/DLC before or post critical story path?

I was just curious on whether or not people planned to play missions after the main story critical path, and their reasoning why.

Personally for me any side missions and any future dlc stories that show up will be played before playing the last mission. I like having definite endings to the story, and I feel most dlc and side missions don't bring a satisfying end to the story. An example would be Mass Effect 2. While the Arrival DLC was more meant to be played after the Suicide Mission I still played it before the Suicide Mission. Arrival as an ending for all of Mass Effect 2 felt underwhelming to me. The Suicide Mission just hit all right notes. It either leaves me satisfied to stop playing or wanting to immediately jump into Mass Effect 3, but never with the feeling of wanting to play more of Mass Effect 2 afterwords.

How do you plan to handle side missions and any future DLC missions? Why? 

Anything after Sanctuary feels weird to do so I go straight to Cereberus when it's done and finally Priority: Earth.

Oh yeah. Hakkon made no sense to just begin during Cory's stuff imo. It was a whole new story with a new baddie.
