I like that they try the idea again. The CoH2 abandon created very tense moments and was quite fun at times, but also very frustrating to lose because of the RNG.
If it does not work out, they could still scrap the recovery. It does not look like any faction relied on it or had it as an integral part of their design. It was rather tacked on to a normally functioning faction.
Having vehicles generally recoverable could mean some good news for overall gameplay. Artillery can not be as strong anymore in large games, because the main counter to arty at least in CoH2 was diving a tank, which in turn is only viable if you don't hand over your vehicle to the enemy. Second, balance must consider units not overperforming in another faction. In CoH2, USF's ATG was mediocre for USF, but one of the best ATGs if you could capture it as Axis.
Obviously it can also mean that if Relic does not consider any of these points enough, it will be a complete fuck up.
That does not make sense. Currently the risk of abandoning a vehicle is quite low. With recovery the chance of recovering an enemy destroyed vehicle behind your line would be almost certain if one's faction have these tracks available.
I don't like the idea of gathering points and unlocking buffs by this, especially not recovering vehicles to fill a bar until you can build the enemy's vehicles. It has too many bad implications: How many vehicles do you need? Do they all count the same? Which vehicles do you then unlock? Do you unlock them forever or only once? Why can I build a P3 if I only salvaged Kettenkrads and some Sdkfzs?
These are question that obviously can not be answered here since the require extensive planning the testing.
A rough idea though would be:
Number of vehicles need to be able to build a vehicle would be according to vehicle category (light,medium, heavy, super heavy).
Nope, when it comes to recovery wreck would only count for the specific vehicle or category.
Vehicles would be unlock one by one
answered in point 3
In addition one could use the wreck for other reasons. For example one salvages a dingo armed with bren now one can equip an infatry with bren, one salvages a hmg now can get a free pintle, one salvages one a PzIV, one can give skirt to PzIV or salvaged vehicles can offer discount to techs.
The recovery cost and fragility of the recovery vehicle will determine how viable it is and where you can use it. It might still need changes, maybe even larger ones, but I'm okay with Relic at least trying the idea if they pay enough attention to the balance and design issues it will cause.
Imo recovery cost and fragility are too few variables to be balance the mechanism across all modes when the price can be something as important as Black prince. Providing more tools would help balancing the mechanism greatly.
