Since it is released, I am playing on ARID and I find it fantastic map but I have to admit that one of the biggest problems about ARID is raiding. I won't complaint about how hard to get crafting materials for raiding items and also I think it is much better in this way, I mean hard way. The problem about raiding is AoE damage of warhead and charges.

Let's say you placed your crates next to the your adamantine wall. I will tell you what will happen after that. If other players try to raid your base, it requires 5 rockets to destroy adamantine wall, and they have only 2 or 3 rockets, your wall won't be destroyed but your crates will. Even they can't get your items you will lose them.

You can craft adamantine safe but it is so hard to craft if you compare to metal safe or industrial metal crates.

Also other problem about arid is "claim radiator". Hard to craft, takes lots of place on base. If you don't have that in your base, a troll will come and place his own structures around your base and basically kill your enjoy.
