Leechers are the reason I hate training non-solo

From ~160-190 the only viable option is HoH. IE if you aren't solo/duo(at best) with 4-5 leechers, training is going to be noticeably hindered.

That being said, and like the topic title clearly states, I absolute loathe leechers. The only thing worse than a leecher is being in a party, and likely the only attacker, and the Bishop has the gall to just sit at the bottom and not at least have the decency to go to the attacker when HS is running low.
