We have events/quests were you can get trainer heroes/master trainers like from the Masquerade or the Trials quest. You can also ‘make’ them in HA.
Would be great to see an event where you can get trainer troops or have them awarded like training heroes are in the current events. Heck, I’d love to see an event just where you got only troops AND trainer troops. Those trainer troops are hard to come by (if you don’t buy them) and you cannot make them in HA either, yet they are by far the most useful resource in the game!
How about we make them more accessible? Troops are costly as it is, those trainers really help out a lot!
