I like the eurcas in the... doh? gates? (The area near the morimar basalt fields frontier station). But you're on asura, so that place is probably going to be full all the time.

If you just want the satisfaction of smashing stuff, my favorite place for off-meta jobs or playstyles is the dullahans and gargoyles nearest the home point in the Inner Court. easy stuff but still good for grinding if you can kill fast.
