I can't say whether it will lead to a lot of camping or not. It'd be nice to get a lot of people in the dev app and give it some good hard testing, although I know it's not the easiest thing in the world to actually gather people up for that.
Base spawning is a good way to prevent players from constantly spawning on each other's face, which has been the biggest complaint by far. As for camping, you've always been able to camp. Even when the spawns were random, each team seemed to have a preferred spawning area. Now you can just choose where in your zone you spawn. Currently the choices have been toned down, so instead of 10 options, you have about 3 or 4.
If you both decide to get into a lengthy sniping match, well; that's your decision. It's risky for both teams, since the enemy has a pretty good idea of where you're going to spawn. Though generally they'll have to move further from their zone to make use of that information. If one team tries to camp and snipe, and the other team has a brawler, getting into the enemy zone is a huge advantage. They have very little choice but to spawn relatively close. Since the defeated doesn't choose their ship orientation, this can be a huge disadvantage. Your enemy, especially in the competitive scene, knows your spawn points, and has a fairly good idea of what you think is going to be a good spot to spawn. You make your choice and suddenly you're under attack again.
It's going to require smarter decisions than 'I wanna be as close as possible'. I've already seen this decision backfiring on players in the current system.
For proximity based spawning, which a lot of players are asking for: I feel that it may give the first killing team to much of an edge. Suddenly a spawn point or two aren't viable, forcing the team to one of the remaining spots; giving the enemy a much better idea of where you're going to pop up. The entire system will have to be done over again. It'd likely turn into something closer to what we have now, with spawn points all over and not just in zones. And players are still going to try and spawn as close as possible, often going for a spot that lets them hit a flank or blind spot. It won't be constant endless combat around the same spawn point, but it won't be too much different than that.
Really players should try out the dev app, check out the spawns. Get some real matches going to get a feel of what strategies will and won't work. Theory is all fine and dandy, but it's difficult to predict how it will turn out. What if your spawn is in a cloudy and crowded area, making it harder to camp? What if you can't see the enemies zone, or have a lot of places they could push into your zone from?
Essentially if we can find good spots for team spawns, we can prevent or reduce the amount of issues we have. It's a good system, we all like having a choice and not needing to rely on blind luck for how the match is going to turn out; it just needs some tweaking.
