First before I address your points I still want to clarify that I am happy Yugoslavia is still being discussed in depth and that I know it brings satisfaction to see your work getting results and positivity. I am not at all against someone else re-suggesting the nation I was just a little confused that they allowed it, even if there’s a new forum, because a passed suggestion is regardless still stored in Gaijin’s suggestions database or whatever they call it.
With that out of the way I don’t agree with your reasoning for having lesser planes.
The tech tree I posted is a community project by a team I’m still part of (it’s inactive at the moment) called the WT Community Council and my superiors had direct contact with Gaijin. I was not asked to join at their beginnings but I quickly caught on with Yugoslavia and Poland.
The sources used for Yugoslavia are extensive books and manuals, so from them I can tell you that the so-called “identical” planes you might be referring to are not so, and you wouldn’t be able to tell through third party sources on the internet. Between the several IK-3 year models and the S-49 series there were important structural and design changes, such as redesigned fuselages, tails, new materials (from wood to steel) and engine improvements, so I have to refuse the points you made to @AspandaIV earlier. Both the DB-601 and VK-105 examples were completed and the 1938 thru 1941 models had enough changes to warrant them as separate planes. The S-49A prototype also differed from the production S-49A enough (couldn’t remember, have to dig again), and the S-49C serie 2 differed from the first one through having a more streamlined design and a better tail for high speed control, while the S-49C-2359 had a vertical wooden stabilizer. These are only a few out of many other instances.
As for trainers, in Yugoslavia’s context for the game, they are still important. Say you are a tanker sometime in the future with a 7.0 lineup, would you not want CAS with it as well? The trainer variant of the J.451MM comes into action here because it had rockets and bombs, not only the G-2. The same applies to all other trainers because even if they’re supposedly specified as “trainer aircraft” they are still quite mission capable and can have their appropriate BRs.
To me the most odd decision you made is leaving out some really important and unique planes such as the Hurricane with the DB-601 and a Hispano that made it 9 guns in total, or the unique seaplanes suitable for naval battles, the indigenous CAS aircraft like the UTVA Kobac or the UTVA Lasta 95, the various Yugo-exclusive bomber variants, etc. Instead you’ve opted to settle for much less in terms of originality, and your tree looks barebones. The only new thing your suggestion has introduced is the relatively new Serbian MiG-29SM and the Me 262 while greatly downsizing the tree.
Both can coexist yes, but know that if you don’t change it, some people who know little about this nation’s game potential may find themselves with a negative first impression if they find this suggestion because this is far from its greatest extent. It isn’t that much better than a sub tree like Israel. In your greatly sacrificed version of the Yugo tree I can only count two or three planes I hadn’t included.
