I'ts been a while I've been thinking about a change in Battlefield Mode, so here is the idea I'm implementing right now: the tech points and support points system has been changed: this is because I've noticed that a player which holds the middle in several maps basically unlocks almost every unit since the beginning. The problem with the current support system is that, to unlock all the support operations, you often have to conquer 2/3 of the map, but if you manage to do that the most powerful support operations are useless because you'll have almost defeated the enemy.
So here is my idea: the tech points as well as support points are not considered as a cap to unlock certain units but they become a new resource. You gain tech points and support points over the time just like command points. Of course costs have been increased, for example now a Tiger costs 40 tank tech points, that means that if you have 3 tank tech points you will have to wait for more than 10 minutes to gain access to the Tiger.
This new concept also allows you to counterattack the AI. Very often when the AI conquers the middle you lose, now the AI won't unlock immediately all the units by taking the middle, but it will have to wait too. So for example if it has 3 tank tech points it will need to wait for 10 minutes to unlock a Tiger, but assuming you have 2 tank points you will have access to, for example, Sluggers in less than 20 minutes so you can actually counter German heavy tanks. This also holds for the AI: it can gain access to advanced units even if it doesn't hold the middle.
The patch will be released soon (7 days) and it will be cumulative, this means you will need to install 2.0 first and then apply the patch.
Awesome, this is way better in my opinion.
A clarification on the new tech system: tech points must be stacked in order to unlock certain units like in the older version, but you earn them over time. You DON'T SPEND them to buy units. So in the example, when you reach 40 tank points you unlock the Tiger, but when you build one, they don't decrease, so you can build as many Tigers as you want.
