So near the beginning of 2.0, Yoshi said that we'd eventually be getting the ability to have our FCs summon Primals. Well, we're nearing the end of the 2.x era and moving on to 3.x this year, with no primal summoning.

I'm sure no one wants to hear about WoW and what they've done, but they've taken that idea and already applied it. The idea Yoshi had was taken and applied elsewhere before we could even see it.

Summon a Raid or World Boss
Players may find an item while completing a Bounty, Relic, Dungeon, or Raid daily quest from the Garrison visitor that that allows them to summon one of six new raid or world boss in the Garrison.
Summoned raid or world bosses have scaling health and is intended for 10-40 players.
Think we can eventually get the idea for our game in our own game?
