Petcuck is so broken. Newest alt is petcuck, has full AAs and pretty good gear. Mage pet with cleric epic + lego gharns, beast pet with lego palladius, necro pet with lego blackstar + rogue epic. Went to sleeper for the first time, had to heal the pet twice the whole fight and it was at most 2 minutes. Did BB too, had to do a lot more healing but still had time to keep dots up, pet was never in threat of dying.
Have all the fotm now, war/bst/clr, sk/rog/shm, petcuck, making a clr/mnk/zerk next have all the items just need to grind AAs and level everything to legendary.
