In the Dev server I find out that some players may have to research more vehicles to get some particular vehicle than now, and i think it can be avoided with a slight fix to the new tech tree.(by the way, most of the new changes are great)
The problem mainly happens when 2 or 3 vehicles which are in front of the particular vehicle (that players is researching) get folded (or grouped), e.g. players that already have ZBD86 can research and purchase M41D with no problem in the current game, even if they don’t have the newly added ZTS63, BUT in the Dev server, as a result of folding (grouping) ZTS63 and ZBD86, the M41D will be seen as linked to ZTS63 instead of ZBD86, so players will have to research and get ZTS63 first in order to get M41D, which may lead to breaking the pace and goal of those players.
I suggest that a light change will repair this, just count the folder as a whole, and as long as the player has at least 1 vehicle in that folder (it doesn’t matter if the player have 1st or 2nd or 3rd vehicle in that folder), players can research and get the vehicle which is linked behind the folder. In that case, players can get the vehicle that they previously researching without being interrupted by the new tech tree changes (i believe that is also what the developers want----to give players better experience).
