Thanks for the input @ats-david. At first I was actually considering the 80D as the specs seems pretty good on paper compared to 7D and I could get the 24-70 2.8 II for a decent price.
But yesterday I went to few camera shops to get a hands-on experience and I must admit the 6D mkII feels great and I think it's time to upgrade to a full frame goodness anyway.
The only negative thing I can see about this camera is that it's shutter speed + buffer comparing to other brands, but not to say it's a problem that will put me off!
The 5D mk iv is a dream but it's just too much for a hobby!
