Depending on your status of imbuements / equipment you should easily be able to hunt walls (i just hunted it on my 260 ek a week ago, 2x life leech, 2x mana leech 1x crit). As skills on that char really sucked it was hard taking 8 but 5-6 was smooth.
Other spawns you could try are Sea serpents (yes even on that level), Seacrests, Oramond west(with raid), Glooth tower, Medusa Tower or Lizard Chosens.
Except for Chosens and Sea serpents i suggest full imbuements for these spawns (+ garlic necklace at medusa tower).
XP at 100% should be ~1kk on Sea Serpents, ~1.2 at Seacrests, 1.4~ at oramond west, ~1.1-1.2 at Glooth tower, 1.4~1.5 at Medusa tower and ~700-900k at chosens.
All of the spaws are profitable except for ora west.
