Hello Ubisoft. I am not sure that you are aware of this fact so let me explain it to you: Valhalla was released on November 10. That's almost 3 months ago. So you know, by now the vast majority of people have completed it and are pretty much done with it.
I personally don't mind Reda's contracts, fast travel to some high point, clear a camp and free some villager, fast travel to another high point, assassinate someone. There, done. 15 minutes a day, 10 opals.
Weekly challenges were fine, bare the near impossible Avenge objective from last week (if RNG was with you and that the stars were correctly aligned). This week : 2 x kill 50 enemies + 100 more assassinations. 50 kills with a spear and 50 more with a Predator bow... why not, just head to Portcestre in Suthsexe, this fort holds over 100 soldiers so you can just walk in, make everyone know that you're here and just plow through everything. But are you aware of the time that it takes to get 100 stealth kills? I am pretty sure that for someone still in the middle of the main story and exploration this is nothing, you'll get them eventually without even trying, but are you aware of the time that it takes for someone who is done with the game and is just going to farm 100 assassinations?
So this week, it was 200 kills total? What's the next goal? 400? Really just make this even more time consuming.
