Played it daily since release - had a week off to look after a poorly pup, so perfect timing really
I think it's brilliant - it seems to have taken all the best bits of the first, and removed [most] of the things that weren't so good. Currently sat in tier 3, and really enjoy how different the world has become, with enemies that are far more switched on and aggressive - though still not perfect.
Things I did/do hate though (PS4 Pro here) - the 40+ Gig download on day one, that is just pathetic, and a sorry state of games today imo. The glitched missions you cannot complete - where enemies don't spawn, or spawn in inaccessible areas (had one under a manhole cover last night!). And the FPS drops/lag - where the game seems to fall down to 5 or 6 FPS!!! Though I think a closure of the game often sorts this.
Though I detests the whole "Year One" pass **** from Rainbow 6, I am tempted to pick them up for Div 2, providing it adds to the game.
Big thumbs up for me.
