I’ve got Boost which has helped and I got to General after 2 weeks (but then this was a normal amount of time for me - pre-pandemic I got to General after around 2 weeks for Ops 1-3 as well), and with the pandemic alot of my old social activities just aren’t happening right now so I’ve got much more gaming time right now. My two dodgeball leagues have been suspended for now, and I also normally go to lots of live music events which again, just aren’t happening right now. I visit family once per week, but yeah… more gaming time! Plus I mostly work from home so often jump on around lunchtime for a short while. I’ve not been playing an awful lot of other games too, so it’s mostly GOW5.
Also there are lots of little short-cuts for clearing daily objectives which is helpful to know. I always see the daily objectives as a means to an end - so I just want to plow trough them. I always look at them and work out what I can do in the same game, so I can minimise the time it takes.
