Hey Hicks, about your questions.
While I am against using beacons in low pop games, most of the time. Sneakers are even harder defend against.
Beacons in low pop as said earlier are hard to disarm if its most of the enemy team against a couple teciesh/hotties. so I never use beacons in low pop UNLESS, their is a stalemate, like a game has been going on for about 1 hour 30 mins and the enemy team is just camping in their base barely surviving. A beacon in combination with a little bit of teamwork might end the game instead of making the game even longer.
Now sneaking in Low Pop is easy. Other than a mine count or base defences, you don't have anything else to combat sneakers. you don't have enough players to find sneakers and cover all your angles. But with no one patroling routes or scouting out places where sneakers are likely to be its hard to defend against them, beacons atleast make a everyone aware that the building is going to blow up in a minute(I think the timer is a min?) sneakers on the other hand are completly silent and only have a 30 second timer. (The C4 on the MCT). So I don't know how much disabling beacons is going to do.
Now if people want a vote option to disable beacons, sure you can have it. But it should be explained that it is on when players join. otherwise you might get comments like, Why are beacons disabled. or: did they remove beacons or something?. Also their should be a vote to enable beacons ofcourse.
Also, The beacon not being disarmable in the final 10 seconds is fair. It makes sense that if a nuke is now above its target its not going to be stopped. same for a ION cannon. Those 10 seconds are basicly just used for the animation.
So I do have to say something.
I mainly play 10 vs 10 or higher. so I don't have any experience with anything below that.
