How exactly does holy symbol work now (Post bb)

He's talking about 110% of the white base experience. The yellow party bonus experience is 10% of that 110%, or 11% of the monster's exp. White and yellow experience combined yields the 121% you are thinking of.

And he's fully aware of that, thus he mentioned the exp size being proportional to the party size.

I wrote something on Basil back in the day, let me pick it up. It's pretty simple though.

Yeah, they still have it.

And it's confirmed that HS' mechanism hasn't changed.

Ah okay, all clear now, cept one last thing. Someone mentioned that its better to have 5 leechers and 1 attacker then 2 attackers / 4 leechers?

Depends on the map. If you can kill the entire map by yourself and keep spawn fresh, 5 leechers would be the best.
