So i love the way ocean drake changes the map it really feels nice, but then you get infernal and it feels like its lacking in the uhhh infernal feeling ? So this applies to other drags as well.
Infernal - The whole lava/burnt theme should be applied across the map, really giving it a sense of the map actually feeling like its theme. Also feel like a lot of the trees in the jungle should be scorched to give it the theme its under.
**some rough examples**
Mountain - Should change the ground completely to rock/sand(Shurima)
Cloud - Im okay with it other then maybe swaying trees.
Just a suggestion :P
