Pets bonuses can be very handy and there are many different bonuses available! Only a small portion of pets have been released so far, so we have many that will be available in the next few years.
I’d like to see the pet that gives the Construct troop bonus come out as soon as possible for one selfish reason: the Hall of Guardians factions already exists and it could benefit from having the pet available to boost the bonus stats.
It is usually a nice feeling when you get a new faction and find some of your older pets are actively applying bonuses to help. Having 3 pets available for All Seeing Eye was such a big help. I would like to see Hall of Guardians receive a similar treatment, being the other originally released faction.
