There is a huge difference, such bonus would completely change your build order.
You say that you have to adjust anyway you build order, and to some degree it’s true, but not that much.
If you are mongols, you may want to go a super fast feudal into scouts, but even a generic Drush open into archer, or a fast castle into knights. You want to do whatever you want with your civ and bonuses, you want to make use of them or not, you may even want to go for the less reasonable strategy just to surprise your enemy.
This bonus remove that, and force you to change your build orders (that many of us memorize before the game) at the last minute, and it still gives the burgundians no advantage.
In fact, such bonus it’s either too weak that some civs will overpower it (chinese, mayans aztecs, italians…) or so strong that it’ll be OP. You don’t want the second case for certain, and in the first case you won’t have done anything to help them.
Also, the TB is fine, it’s free food and it never hurt, and if you really want to buff them just add a standard bonus.
Some examples may be:
-
Stables cost 50% less too
This allow to save some wood (88w), that can be either used to build more stable (you can build one just for research techs, so you don’t idle your production) or to invest in those early eco upgrades, so you can more easily research bowsaw, or heavy plow, or simply more farms. -
Light cavalry can be researched in feudal age
This one is in line with early cavalier. Researching light cav would present the same problem of researching bloodlines in feudal (since it takes about the same time), so it should be paired with the first bonus, but it would be cheaper than BL, it would add +15HP (so 5 less than BL) and it would give +2 attack. The downside is that LC is slower than scouts, but it would make your scouts more effective against feudal age units, without making them OP.
Change flemish militia UT in:
- All vills have a key to be individually transformed into FM
- All archer/xbows trained at the time are instantly transformed into HC
Apply those 3 changes to the burgundians and they’ll become a much more solid civ.
