Yes, mindanao could use more GV action.
My view on the complaints about mindanao is this:
Its a map where furballing is NOT effective. Fields are usually taken after HOURS, if not a whole day of furballing. Or when an organized or semi-organized group go and attack the field. The fields are also layed out VERY well. No side has a marked advantage nor a clear cut path to win the reset. The only bad thing I see in mindanao is that the left side of the map is too easy to defend.
Its a map with many raised fields and rugged terrain and defenders can take off from a raised field near to it to help in the defense.
Compare that to NDISLES, where CV furballs and CV-flak cover are what gets the winning advantage & that fields are only reachable by one or 2 other fields (aka whoever gets the biggest furball wave over the other's field usually wins)... or to Baltic, where the fields are laid out in such a way that pushing for a reset always requires taking the same fields... or to the Uterus, where the front lines are clear cut and narrow, making the fight for each field be just another huge furball.
Mindanao is the only map where you can actually flank, go head-on or encircle the enemy fields.
