So much tasks so many worlds. So many battles I have done. It's tiring!!!!!!!!!
That's the beauty of this game! There's so many different things to do... granted sometimes it may seem it takes forever to get through a world, but you look forward to the next one. :) I do!
If you need a break from battling - there's other things like:
pets - hatching, training, derbies...
gardening - various plants, harvesting, etc
crafting - the quest assignments may seem tedious, but you can craft all kinds of things too
Well that's the whole point of the game. It is supposed to be fun. If you think it is too much you shouldn't play anymore because you won't have any fun if you keep on playing.
