I actually disagree, it’s the opposite

You can bust tigers with a 20mm now, 37mm is just that but on crack.
They will probably nerf this sooner or later (sadly). I fear it’s a bug, because of how stuarts can explode tigers in Berlin: I believe devs messed up their rounds power, HE ones at least.
So we enjoy it while we can, but I don’t think ppl should buy those planes to bust out tanks… as it might get “fixed”… 
Granted, was exaggerated. still, IL has better sights etc. for ground attacks.
If your flaps suck, then it’s pointless to dive. Rockets do a better job. Most tanks in Berlin spawn on roads and hills. It’s not that harder to kill them there because the clutter is the trade-off for (slightly) better cover for awful mobility, at least if you can kill them with cannons at same time. It’s harder to kill infantry there unless in mud map where most cps are semi-small open areas for reasons.
If people are able to snipe infantry and tanks with a 37mm, then it shouldn’t be that hard to kill a bunch of Panthers with 50-100kg bombs and rockets.
Will eventually be reverted so I wouldn’t count on that long-term-wise. And still, if people can do that, they should have no issue to use bombs there.
