Is heroic pets only for a glow and AP?

[yubaraj]

I am not starting a drama here.

Can you STS please tell what is the main purpose of heroic pets?

I have done a stat comparison and the overall stats are not even competent to legendary pets.

I won't be using its happiness bonus and AA.

It is mandatory to have heroic pet now because of AP.

Why the drop rate is very very low as it doesn't stand above legendary pets? I know what I am talking here.

It needs a serious buff if STS wants us to use this pet imo.

Thank you.
