Constantly when upgrading vehicles near top tier I find myself running into this issue. Gaijin gives you stock IR and Radar missiles now which is good right? Except when you do finally unlock a missile mod to give you more missiles, they often ONLY go where said stock missiles are located so you can’t actually expand your missile loadout. Here is an example with the Su-30
Here I have the 2 stock R-73s and 2 stock R-77-1s and I’ve also added 2 R-27ETs as I was allowed to once I got the mod. However, notice this:
I unlocked the next mod, which is the R-73, so I should have 4x R73, 2x R27ET, and 2x R-77-1 right?
No, I still have this loadout:
because when you go to place the R-73s, you find gaijin has lovingly put the R-77-1s where the other R-73s normally go so you aren’t capable of using the new R-73s without completely throwing away your R-77-1s until you unlock that mod.
They did this with the F-15J(M) too, where unlocking the earlier missiles does not allow you to actually add them because they would go on the pylons the stock missiles take up.
Gaijin needs to consider mod progression when they implement these stock missiles and put the stock missiles on the pylons that would cause the least issue with adding newer missiles as you unlock them through the modification tree.
