Monotonous Farm ways ala Diablo2 AND crisscross Farming is time to make cool mixture. In Reaper of Souls is highly set to group game, and I find that amazing. The game has become real hammer, I would even say that it is almost better than Diablo2 LoD up on missing Runewords.
Only drawback is that still the group match is limited to only 4 people, so 4 stars.
Nevertheless, a buy recommendation!
