Hi,
Looks like you already signed up, when the first LB races for smaller prizes started last year.
If you try with free, pre-made heroes, I recommend the Dark Elf Cleric, and focus on the Zombie horde tourneys, and 2 players SNGs. so you mostly will compete vs. more weaker npcs instead of more strong, unique real players. In this way, not hard to climb ranking LB. Atm there are 3-4 guys in top10 with free heroes.
I did sign up about a year ago, but then I got confused.. and then sidetracked by health issues a few months after.. still dealing with that shite 🙄
Thank you for the recommendations, I'll keep it in mind 😊
