LotL is a great, versatile hero. Without Telly or Heimdall, she is my tank and does better on defense than Kunchen in the current meta. She is awesome to raid with, use on Emblem quests, Raid Tourneys, Challenges cause her minions just control mana so well.
On Raid Offense once you’ve kill off 2 of the opponents heroes, you can just keep ghosting green tiles and setting her off to generate more minions. Once you’ve gotten the opposing team down to two heroes, neither will ever gain mana before you kill them as long as you keep ghosting green tiles.
I had a horrible board towards the end of one raid where I just couldn’t get tiles for my snipers and only LotL kept the raid going with her mana killing minions so the opponent never fired until I could finally kill them off.
