1. Marshes. This is the best map out of the bunch. There's a great mix of open areas and cover, the water helps conceal tanks, the absence of annoying LRM spamming VTOLs is great, and it looks awesome.
2. Sandblasted. The little buildings are great, there's a decent amount of cover, and it looks great. The only problems I have with it are the LRM spammers that camp right outside their base.
3. Inferno. There's almost no LRM spam, so it's high on my list. The only gripes I have with it is the limited color palette, and the buggy heat (randomly overheating even when nowhere near lava).
4. Extremity. It looks great, but the lag shields on BA and the sheer length of time it takes to get anywhere ruins it for me.
5. Clearcut. I hate Clearcut, it looks great, but it just degrades into LRM spam, tanks get stuck on everything, and it causes my display to fapp up.
