I think the terms here are getting a bit confused…
There are 4 different sorts of tasks, but players don’t really seem to distinguish between them. That’s the first thing to correct. I’m hoping that the new system will make it very clear that the first task is a “daily challenge” that you need to do ASAP or lose it, while the others are “chip away at this” sort of tasks.
Trying to win 5 defense battles TODAY? - That’s frustrating. But getting a challenge to win 10 defense battles over the course of several days or a week? Much more reasonable.
The new system has tasks like “Win 20 battles using 3 unique troops from Adana” sitting next to daily tasks like “Reduce an enemy’s attack to 0.”
I’m also trying to smooth out the transition from linear tasks (that you only get one time) to repeated tasks. Used to be that around level 50-60 you were thrown into the repeated tasks. But now I’m trying to extend that to about level 150. Which means the repeating tasks can generally be more challenging (read : “fun”) even for very high-level players.
