Death vs Nature unbalanced?

[Anskiy]

I feel like the Death realm is rather weak to Nature actually, in a lopsided way. The main problem with a lot of Death's summons is that they have pretty bad resist, and no way to raise it really outside of heroes or spells from other realms. This means that armies of Cockatrices become incredibly effective against them, as I discovered the hard way in a Death game that was seemingly going well. And woe to you if they have Focus Magic on them. But that's not all! Nature also has the best single target save and die spell in the form of Petrify, which wrecks even Very Rare summons in Death, and Gorgons, which have a shitton of attack and a stoning gaze. I don't see what options Death realistically has against these, maybe packing a Prayermaster hero? Massing up Night Stalkers with Cloak of Fear and Black Prayer?

How about Black Sleep? 50% chance to kill a cockatrice without, 70& with Black Prayer.
Gorgons still have fairly low resist for a rare summon, 30% chance to sleep, 50 with Black Prayer.
You don't need to use your good creatures against Nature because you can kill theirs with spells easily so it's best to rely on cheap, disposable units like undead. Or you can raise units with Stoning Immunity as undead, like Stone Giants, Gargoyles.
Death is weak against petrification but has plenty of ways to work around that.

The problem with the proposed solutions there is that I have to first cast Black Prayer, then roll the dice, then hope a unit gets close enough to kill them. All of which are rather hard and dangerous to do when facing against an actual wizard. Further, if Death is meant to counter Nature, why should their good units not face against Nature wizards? That doesn't sound very intuitive to me..
