When I first started playing I farmed for recruits, swords, and packs. I wanted to level heroes as fast as I got them and needed constant feeders. I started farming for materials for events when I started competing. I would need 200 axes, bombs, mana and 100 dragon attacks each month so it takes a lot of grinding for roots and lumber. Now that I’m not competing as much I farm for nuggets. Hitting titans is more fun with nuggets.
I used to finish all the quests but I don’t care so much for most of them anymore. I don’t think a players level really means much. I used to rely on leveling for titans though. I would try to time it right so that I wouldn’t waste flags.
