A year or so ago, brumbar vet 2 have 320 armor.
What made brumbar viable that period was the aoe change doing more damage.
Of course relic than quickly nerfed it before the anniversary 2v2, by reducing its range 40 to 35. And reduce armor to 240 and armor vet2 to 288.
This change only revert the armor nerf, not fully even.
The loss of its range was and is still making it a tough choice. At least against something like 60td Jackson with vet pen/rof
Except the Brummbar is fine in terms of damage. The main issue is the bad trio of bad range, bad armour and bad mobility, so the armour buff should be enough to allow it to do its job, especially vs enemy army comps that don’t have enough AT power.
