1. lvl 1 mules should be rushed to act5 with another char (rusher), then you should enter with gater and share your baal q
2. no, kill ancie and get lvl 40 @baals
without getting last quest (killing him, or being in chamber with someone who will kill him)
3. i think expansion's market is softer and it's easier to gear decent rushers with minor budget
whats your final task? sell bumpers or fast leveling in hell cs?
