I love this idea and I'm sure you'll balance it better as time goes on
I'm not complaining, this is only a pro, but I'll compare the JTs you could get weekly before and after this patch
Before:
Asylum Bronze 50JT
Asylum Silver 150JT
Asylum Gold 200JT
Baylan Bronze 50JT
Baylan Silver 150JT
Baylan Gold 200JT
Boss Tier Daily Activity 7 x 25JT
Tier 5 Daily Activity 7 x 2 x 20JT
Tier 4 Daily Activity 7 x 2 x 15JT
Weekly maximum: 1465JT
Now:
Same as before, 1465JT plus average JT earned by new system
What do we take as average? According to my own experience and what I heard from other, with this system you average 1-2JT per mission. I have played 16 missions today and got 14JT in total so I'm even below this average. Let's say you still play the same amount of time as before. To complete 5 Daily Activities maybe you played 10 missions total. These missions would have given you around 15JT. Throughout the whole week this is 95JT
New Weekly Average: 1560JT
My point is that the increase in JT obtained is barely above 5%. Which is too little to even consider. I know I "made up" some numbers like the JT average or the missions an average player plays per day, but I don't think they're that far off.
Those caps are weird too. Averaging 1.5JT a mission, to get to the 200JT cap you would have to play more than 120 missions. In a day. Why does that cap even exist? Either they messed up the drop rates/the amount of JT given or I have spoken to a lot of unlucky people.
