Why seraphim glaciers doesn't belong in the ranked? (Answer: IT'S OP WHEN YOURE PLAYING AS SERAPHIM)
1. First of all, the map is way too big for ranked where you are looking for normally 30min games at max
2. It's all water, which makes it way too easy for seraphim units like zooeys (easy map control and devastation of enemy mexes on islands, no need to build t2 fac for floaty units, nearly hard to counter easily and mass-efficiently)
3. Once the game gets to the end game, well again the map is all water, you will see sera t3 subs and the game is all over.
4. The sea causes problems later on when for example a sera T4 bomber kamikazes your base and leaves no wreck since it falls to the deep sea (win - win situation to the sera, no wreck left for the other player to reclaim, which certainly should be a matter to consider when sending a such a glasscannon to another's base)
Also, this replay shows how a "strategy game" can be won by spamming the OP sera units that require next to none tactical eye. IMO the game would be fine without the 4th race.
I am welcome to comments on how the game could be won by the red player? Pay attention on how the dominant navy becomes obsolete when the blue player starts to spam t3 subs.
It's clear that the blue player has better eco in the end game, but is crippled several times to the same level as the other player, and rebuilding takes mass, so that shouldn't be the problem.
