With 44 zombies in Their Method 22 of them are males and 22 of them are females. With that being said you still have the factor of pots, SCC would use more. Things like nao stones, pet rez kits all have to be abused, then you have the trouble of multiaggro. Sure its better exp but for x10 more work?
Well, many of the groups only have melee monsters only. All you have to do is WM.
The ones with 1 archer, just smash it and then proceed to WM. Two Archers, you may need to range one of them out if you are unsure of yourself (or don't want to use pets).
Only major multi-aggro problem is the 5 archers if you not really good at pet play. Sitting back and ranging them is safe if you are don't have the confidence.
Ghost is really easy since it is alone and slow. Just smash, use pet to distract with a single hit, and smash again. Repeat till dead.
