Tundra, needs alot of improvments, there is no sap or Organic Past Source near it (South Tundra), no Metal and less Fiber than anywhere else.
Compared to Tropic it´s just a bad joke.
You even need Organic Past for Fur Cloths, unless you want to life more than 5 min.
The entire Map is claimed so your forced to go there if you want ground, and there is no chance to win a temperated or tropic island if your behind, even more so, knowing that fire arrows are op ...and need sap.
If you know any good sap spawns close to tundra feel free to share. I only know of E5 and E7
