I can see how a larger territory might be useful, but personally I wouldn't want it much bigger; at least not without some other way to lose aggro'ed monsters on my trail. For instance, if I'm doing a difficult leve and I accidentally aggro a surrounding monster without meaning (darn Billy Goats for instance :[) I would like the chance to run away before they kill me! If I could hide behind a rock until they lost interest, okay, but even now I need to run a long way away - not to mention I already have to be careful not to run in the wrong direction because I can accidently run outside the leve area and lose it (have done this - it is frustrating...).

However, when I Gather, I'd like to be able to pull aggressive mobs away from my leve spots please - without them sauntering back and whacking at me while I'm logging. So in that case, slightly larger territories would be nice...
