Oh and for eggs, arc sapphire is great as base pet, HB also the ones listed above are good, if you go for Heroic Sabra and you have a little time, wait till catacombs come back start of January and it will be cheaper than it is rn. For AA i usually run H Tadhep/H Pere for Haste, Arc Werewinger for more boss damage or simply H ghostly for more speed, there is many viable options though.

As for gear, Kraken armor + Staff for mobs, Gun for bosses, if you got extra cash getting full kraken surely is beneficial, once you proc your kraken armor + gun/staff - switch to something like zaarus set for more damage (Zaarus is a cheap option), with the new sets there is also better options to switch to if you have enough cash.
