In my opinion, the buff to the Leopard 2s still doesn't go nearly far enough. I'll have to play with them more-- maybe it does work. The killing capability of NATO high-tech MBTs should approach ridiculousness if they are not suppressed somehow.
Even the Chieftain is supposed to have a 98% hit chance at 3000m, the MRLS have 644 submunitions in each rocket, etc... Thanks god the devs favored balance over realism at all costs, the fights are brutal enough now.
I think I would take the realism over gameplay balance because in real life you wouldn't get so many latest modern units.
The rocket fire is deadly in real life and it should destroy almost anything on area what just is there. But in game it should be as costly and slow as it is in real life. So you do not just shoot, move and shoot again. But you almost only use those units once or twice and then you can not afford to fill them.
