No there not each week 26 Quests. Looks like currently more Quests available then it should be, but we checking this currently.
You still need to do all quests which appear.
What about the fact that pandemonium quest doesn't count for asmodians? I should be at 14/60 yet the grand total shows 12/60.
We are aware of this and currently checking it, why it doesn't counted for the Main Quests. But the progress is saved. So nothing will get lost.
To the concept behind the HT I won't discuss, but we all still open for feedback.
