Its certainly both a sequel and prequel film but i view it more like a comic one shot.
Maybe you'd have felt different if we got a series of FC films with cast for a film or two clearly making it their own franchise
I don't think we can also view DOFP as a prequel. The first three movies had scenes set in the past too. DOFP will be similar to that when we see scenes set in the past. Then time-traveling to the past and changing the past also rules out the definition of a prequel. When the future X-Men go to the past, they are rewriting the history. So the film won't just shows things that already happened in the past. So it cannot be considered as a prequel film.
And maybe I'd have a different opinion if the cast of First Class got their own series like the original cast but no. That didn't happen. So First Class was just a prequel, not a separate series.
