How can I increase my chances with Hero Gold tickets?

I am not aware of any times or methods to improve your chances. The return from tickets is random and based on (very low) probabilities. It is possible to get 2 orange heroes in 2 tickets and then none for a long time. It will take time and a lot of tickets (or buying a lot of tickets) to get the heroes.

The only way to guarantee orange hero drops is with the special tickets that you can buy or get as rewards in the Doomsday events.

I bought 30 Gold S2 tickets for € 109.99, unfortunately there are 29 hero green and blue in it and an orange, no S2 hero. although for S2 Hero the tickets are sold! That was my 2nd experience.

Wait for the events that have luck when you draw... First week of season x and such. Basically Everytime you draw a normal super recruitment you increase your luck, about 200 normal super recruits would get you a legendary (formerly gold) season hero, around 700 to a thousand (1000) gets you ten of them. At full luck there is a 100% guarantee of a season hero so try to get as much, or save, super recruitment tickets and use them at these events. Good luck... Shadista of state 557
