Mr. Anchor is awesome.
His Hp:Exp is not. But pineapple you hit both platforms with heal.
So imagine ALWAYS hitting 6 enemies all the time without EVER having to try.
That is Mr. Anchor.
It really is nice mindless exp.
Also you need to be on the top platform to hit both rows.

Himes will be your best bet as far as fast exp without leech, but if your just going for mindless then certainly Mr. Anchors are your target. I'm also a 88 priest and although it'll be VERY slow you'll be able to train mindlessly for hours there
