Why not if the JT requirement is high enough? I'd rather grind tickets than check for daily activities.
Well it's possible, you have to remember that you may face a cheater or team of cheaters who ruin your winning streak regardless if you're skilled or just lucky.
At least this, they should remove streak challenges and duplicate activities, we can't currently do anything with duplicate rewards. Checking for rare activities daily is boring and frustrating as getting one is very rare, it enslaves you in a wrong way.
