...this would lead to another problem of having such solution on one map and not on another, and in the end we will need to rebuild whole game.
Doesn't need to be a problem at all, more like a feature. A larger map doesn't need those things, as there's plenty of options to choose from (and enough lag causing objects on them already
). A smaller map (like Luttich I mentioned) could benefit from it much more...
The developers of Red Orchestra made destroyable parts of walls that can only be destroyed on some maps, yet I never heard of people nagging because of inconsistency.
Besides, we already have those silly planks on Giarabub, why not have something similar for tanks on other maps...
I understand the maps would need to be reworked to a degree, and further testing made to make sure it doesn't break any balance. But still I wonder...
