But then we lose all those going for the alternative method. Its not like unguarded mines are always full of players as it is. Further de-population would just weaken the concept.
That's because unguarded mines are mostly rather shooting ranges for BKs than battlegrounds.
There would be more visitors, if high minigun level could be defeated by strategic hiding skill - like with double entrances at Redding or Gecko, multiple mining spots, view obstructions for successful hiding, like trees, buildings at Redding or signs at Gecko, as well as less bottlenecks, like at Broken Hills with its sole ever-camped entrance.
You could ask players for more strategic nuances at mines, but that's a different topic.
As for the original topic, i can't imagine that the players would resort to more difficult and timeconsuming ways, which i proposed, just to avoid being lolslaughtered by minigunners camping the grid.
Otherwise i'd like to quote following:
