Fixes and nerfs
If you only have 1 pet summoned, nothing changes, but if you have 2 or more, the pets lose 5% of their stats for each of them (max 5 pets = -20% of stats)
(reason: I don't see how well it will work yet and that's why I give 5% per pet, but it can be more or less, after all, at the maximum amount, it's 6 enemies against 1 target)
Selection of pets: it would be possible to choose it directly from what you already own in the form of Beastmaster's Whistle (and the like), but you can still only choose from those which tame skill you have (so Tame Beast = Beastmaster's Whistle only)
If you want to tame a pet that you don't have in the form of a Beastmaster's Whistle, it is still possible, just this pet that you would tame would be automatically stored in the stable where there is room for up to 25 pets, while each Tame Skill you get +5 slots.
Choosing the pet you want to use would be similar to choosing totems. the first choice would be beast or dragon or undeath or demon or element or summon (humanoid/mercenary is not in the game yet and I don't even know if it will be) after choosing one of these variants you will be able to choose a specific pet (the variants are unlocked again depending on what you know for skills)
Summon is a specific pet that you summon immediately now (not 10 sec cast) and it is Summon Felguard, Summon Felhunter, Summon Imp, Summon Succubus, Summon Voidwalker, and they do not have access to pet talents and abilities(custom i wrote) but it is possible that their abilities can be transferred to other pets and they too have gained the abilities of other pets also they don't count as pets so you can have 5 of them without the 20% penalty for them.
Specific talents for pets such as Power of the Elements (elemental) are governed by the pet you assigned to the first slot (water element = 5% heal -5% mana consumption) and this also applies to summons (Master Demonologist = Sucubus +5% damage and crit chance with shadow spells)
Talents that the player has that strengthen all pets work for everyone, but talents/abilities that only work for specific types of pets (Soul Link) -!!do not change!!- (maybe just numbers as a nerf)
Limited Summons can be placed in any slot and only 1 Summon can be summoned at a time, and in order to distinguish them, they will have an hourglass symbol (again, their abilities can be shared with other pets and they also do not have access to custom talents and abilities)
Who belongs to Limited Summons : Call Fungarians, Force of Nature, Summon Water Elemental, Shadowfiend, Feral Spirit, Zulian Guardian, Summon Gargoyle
They mostly all have a 3 min CD or less still works and this CD will carry over to your summon/recall 1ST pet ability (which you learn with the pet and doesn't have a GCD)(PS 1ST means first slot so if you put this pet in slot 1-5 so the CD will be for 1-5)
What did I forget?
