It was just a thought I had at one point, but why not have hosted events.. ..say a "mini pug" on a certain day, say fridays. where a singular map is played a few times with a group of dedicated players. it would be like the normal pugs but every week the selected map could rotate to a different map on a list. (essentially the same map would be played for that day)
for example:
-Week 1: walls
-Week 2: eyes
-Week 3: storm
-Week 4: cliff side
-week 5: under
-week 6: (custom community made map)
after the list is exhausted it would restart from week one. this would give more maps attention and might help shake away some of the staleness of playing the same 3-5 maps all the time. (then again, i am also biased toward certain maps ill admit) And adding in the community made maps might be a way to freshen up the experience by trying new things as well.
having said all this, i haven't shown much interest in normal pugs before so im not 100% sure exactly how they are managed rotation-wise, so if its already like this then just ignore my words.
