Eggzavier and luck reroll

[Ebereasider]

As with every event, some people again keep saying that reroll making their loots worse and they are looting better pets without reroll. Some of them keep pestering me to change my luck pet at boss as it is changing their supposed 'arcane' pet drops into 'rare'. Looks like these people are totally ignorant on how the reroll mechanism works, so here you go:

How it works currently:

Mobs can have multiple loot tables. Rerolls happen independently within each loot table.

If you get an item from a loot table, reroll behavior is different based on the rarity of the item from your initial roll.

common, rare, epic: If there are items of the next better rarity in the table, you get one of those.
legendary, mythic, set, spirit, vanity: Roll again on all items in the loot table. If the resulting item is a better rarity, you get that instead.
arcane, heroic: no reroll, you get the initial item.

So if you can read and understand english, you'll see that it will NEVER reroll if your original loot is arcane or heroic pet.
And reroll NEVER gives you an item which is lower rarity than your original roll.
If you are looting good pets without reroll, that only means you are fortunate enough to get good items on your original roll

All in all, reroll doesn't guaranty you the best loot, you can loot good items without using reroll, reroll only gives you a 2nd chance at better item.
Lastly, if you still refuse to believe or if you are superstitious about reroll, here's an arcane egg drop after reroll:
