A limitation of the way the engine handles surfaces right now I suspect, but it's certainly counter-intuitive. Whether it's a balance issue though...
Honestly, I kinda intuitively expected Atlas to be vulnerable to anti-air.* *Yep, SC2 player here. Also seen Donkey Kong, I know how that stuff works!
It is true, and I posted another thread about this. When it is in the water, you can only attack it by bomber or torpedo weapon. Some arty unit or building which can attack the submarine should also be able to hit it. But I find out that the Atlas is not too hard to bring it down. I have already killed 3+ enemy Atlas in 1vs1 ranked game, one of them is in the map Meso. I lost the mainland of the Meso, but I hold the most of the metal of the ocean. The opponent made a Atlas and sent it from land to my base which was in the ocean. I originally tried to test whether I can kite the Atlas by submarine or not since the submarine has better range. But the Atlas received too many damage from my battleship and Ares. And it just got killed by submarine as soon as it walked into the water, so I still don't know the answer.

And I am sorry that I forget some details of this replay, I bring the Atlas down by Orca rather than the submarine. I am the green, and the opponent is the brown. Now you see the Atlas. Few seconds later: Now it is down: Unfortunately, the replay doesn't show the content of the chat. I remember the final chat is about this. (After bring down two titans of my opponent's...) Him: The game is too long! Me: No, you will lose. Him: Why? Me: Because I get more metals. (Few seconds later..) Him: WTF! Well, GG. (The commander is smashed by Atlas.)
Thanks! It is so cool that titans are getting used in 1v1 ranked. I really wish someone was casting some matches. There is no video content for PA:T at all!
None at all? Here's a few: https://forums.uberent.com/threads/beerforkids-pa-casts-and-videos-now-60fps.65035/page-5 http://exodusesports.com/videos/
