Stratus Ice is meant for competitive play, with balanced being the first priority.
Each main is on low ground, with a ramps leading to high ground. On this high ground is another ramp leading down, allowing wall offs choices to have an added complexity. If players choose to wall off at the second ramp, this will leave a small flank route leading to the main.
The middle area is relatively open, with a large ramp in the middle. Side paths lead to back doors to the enemy's natural, and are blocked by 2 mineral patches with 100 minerals ea.
Please check it out in-game before ripping it to shreds :).
