For me its always been game mechanics and fun over lore and realism, any day, any game. I don't really care how one would justify it but I'm pretty confident that a "reasonable" explanation can be thought out.

I simply want a height limit to drop uplinks. About 2 stories or so higher than the adjacent ground. The rooftop/tower camping mentality is a virus that this game sorely need to lose.

Ambush: Flies up on tower or climbs up on rooftop and drop links. The game slows down to a crawl, its very boring for the guys on the ground having to either just get out of reach, or climb a ladder which is camped from the top. Its also extremely boring for the few guys who prefer a short range face to face fight. What happens when someone is brave enough to jump down? They get insta dropped by the 10 enemies waiting below.

Domination: Much the same situation as Ambush, only slightly worse. The first team with the good DS squad will normally sit up there raining down death and boredom to both teams. very often in both Ambush and Domination, its the roofcamping team that loses, at least that's my personal experience.

Skirmish: Fly around the map at the start of game and place an uplink or two close to but high up from all the objectives and you're more or less guaranteed a win as long as your bluedots at least tries to hack stuff. In this game mode I don't have an especially good argument against it, cause in skirmish this can be countered by flying around dropping flux nades.

In Dom and Bush you can easily get into situations where its impossible to get them of the roof short of getting an OB, there will be multiple forge fatties waiting to shoot anything out of the skies long before you can fly up there.

Consequences for gameplay: Bare with me on this one. Try to imagine what it will mean for the game to not allow uplinks in high places.

1. Deployment of uplinks would be much more tactical, rather than the usual "put them on top". Ideally, uplinks should scale from militia to proto by getting less and less DB, and possible spawn time/numbers too. Imagine a 15 DB proto uplink that can only be detected by either a Gal super scanner or not least by actually looking at it. This should scale downwards and we'd have a sort of Equipment-Ewar going on. This will furthermore reward situational awareness and people would need to interpret enemy movement. Where can that link be?

2. Now camping on top of something would have a risk/reward factor, well, sort off. If you do set up with multiple hives, a dude with a scanner, a dude with a forge, a sniper and whatnot. If someone either falls down or get countersniped, it's gonna be a beach to get back up there again. He'd have to call in a new DS and so on.

3. Will this change average player mentality? "Nah, its such a hassle flying/climbing up there I'd rather actually push the point and go for the win instead of pathetically trying to pad my KDR..."

I sure can dream....
