I’m sure you’ve seen my NK sub-tree suggestion, but I’ll comment here as well.
NK and SK have no technological relations. Sub-trees are, in virtually every instance, given to countries with either a) close technological relations or b) close international/geographical relations.
NK and SK only have geographical relations, as well as (obviously) historical, but we all know both of them are not pushing significantly for reunification (actively threatening to go to war with each other) and neither have any shared technology.
SK tanks are US inspired/imported, and NK tanks are Soviet imported and/or Soviet/Chinese inspired.
It makes little to no sense for them to be together in a game like WT.
Examples of sub-trees to back up my argument:
UK – South Africa
- Close international relations and history together (even despite the horrors of colonialism)
- Close technological relations (Olifant based on Centurion, British guns + ammunition, engines, etc.,)
Sweden – Finland
- Close geographical and historical relations
- Some technological similarities, albeit slightly more limited
Italy – Hungary (in future)
- Close relations as part of the Axis during WW2
- Limited (at best) technology sharing
There is a formula. Sub-trees are given to nations with at least 1 of these traits: close relationship (e.g. as allies) or similar technology, or both!
The only “sub-trees” that go against this formula are Taiwanese vehicles in the Chinese tree, and a few DDR tanks in the German tree. But, I would probably argue that a) Taiwanese vehicles shouldn’t be in the Chinese tree and instead should perhaps go as a US sub-tree (perhaps the same with SK tanks) and b) DDR vehicles should be split, so DDR + FRG vehicles are separated in lineups and such. But, Germany has a stronger claim to have both, as they have been unified for 30+ years. Korea hasn’t.
NK and SK are not allies – obviously –, are technically still at war, and have no technology similarities. Not to mention the presence of copy-paste, very few low-tiers, etc., a United Korea tree just doesn’t seem like a good idea. So sorry, -1.
