I’ve also seen numbers 2, 3, and 10. I’ve never tried quitting a PvP match so can’t comment on 11, except that “PvP is so luck based” implies there are parts of this game that are not so luck based? What?
Here’s a screenshot illustrating number 3…
…which leads me into…
13: Win 20 invasions task requires 40 invasions. Either make it actually 20, or increase the reward, because 40 is kind of a lot.
At first I thought maybe the “Win 5 defense requires 3” thing was a too-subtle Monty Python and the Holy Grail reference, to go along with the Holy Symbol and the Knight Coronet, but then I saw the “Win 20 invasions requires 40”.
14:. The “Win any battle with the banner from <kingdom>” task is incredibly unreliable. I can win battles with that banner for hours and the task never completes. Actually the whole banners and kingdom-mana-bonus system seems screwy.
15: The “Champion” achievement is similarly buggy. I had challenges mastered all over, including two full kingdoms’ worth, and no achievement. Then I beat the first challenge in a new kingdom, one star, and the achievement unlocked.
