Sme preliminary thoughts on the lockdown maps. This is from the perspective of someone who plays guardian- I'm very sensitive to the effect of movement speed, as well as the tension between capture and damage stats.

Mines
I really like the addition of rockets to knock people back, and the plethora of narrow hallways makes it more likely that rockets will hit. Gunners will love those areas. One problem I ran into, though: the locker room entrance is too narrow, and in one match, a nimble guardian/ shock bomber duo was able to bottle up our respawns. (this isn't the only map that aids spawn camping, but it's the only one that places ammo outside to make spawn camping easier) Because rockets can be thrown farther than guns shoot, might I suggest that the rocket pads be placed inside the locker room? This would make it harder for opponents to hang just out of gun range while waiting to kill respawns. Having rockets inflict stun might also be thematically appropriate.

As a slow walking guardian, I had some trouble given that this map is very.... elongated, with a lot of fighting areas that are very far from a capture point. During one match, roughly half the players switched to striker to join an endless melee in an out of the way spot. It definitely impacted our teamwork where captures were concerned.

I like the clearing with pillars in the center, but the cover it provides might favor sword strikers on a map that's already movement-speed-centric... Putting spike traps or even unquenchable magma in random corners would offset people who randomly dash around, and reducing the length of the hallways would encourage people to fight near capture points. This will be a great spot for bombers, though, especially as people get their bombs heated to level 10 for the ctr bonus.

Stadium
There's a lot of new stuff in this map, and overall, I like it. Traps and walls are thoughtfully placed around control points in a way that forces people to attack sideways, cutting a lot of the fake advantage of attacking (or defending) from below. The rocket pads behind a fire trap promise to generate hours of schadenfreude, and while team barriers are still new to me, I really like the attempt to discourage spawn camping by granting very clear advantages to one team near their home base. The video screens and cheering fans also lend ambience.

My approval of this map has just two caveats. First, all the awesome new stuff is a bit laggy, and none of the graphics updates have ever done anything for the effect that fire/status pits have on my frame rate, even on low detail. Complaints of lag were common from players during my match. Second, the southern corner capture points are weirdly out of the way and down a long series of isolated hallways; players who go to capture or check these points are basically out of the fight for quite a while by lockdown standards. I'm not sure if I like the implicit promise that the point will be captured between when I notice a point has fallen and when I can arrive to defend, but I suspect that recons would thrive. One way barriers could be used to create a better shortcut for the home team, though making travel time too imbalanced might just put the point out of contention altogether.
