[possible issue] heroic pets didn't get significant improvement at l50 passive

i remember dev said that l50 heroic pet's passive will make it gets significant boost in damage or something different about its damage calculation

but after testing on two heroic pets, tyrannica and vlad, i didn't find the advertised bonus, no increased damage (probably only +- 20 damage, tested on elite brackenridge, but that's more because of simple pet's level up), no increased passive effect (in case of tyrannica the armor debuff is still -15% no difference to l40 passive), and (it seems) no increased chance too

also is tyrannica small aoe attack intended? other ranged pets (e.g. dauphin, ribbit, cinder, malison) doesn't have trouble destroying closely grouped barrels, but tyrannica does

please check it again, thanks
