4star silver tokens - where have they gone?

It's quite clear that these are some of the most sought after for any player - and without them you just hit a wall at trying to get anybody up talent wise. I appreciate there have been 5 star diamond tokens, a few 5sg tokens in events - but I'm seriously trying to see how on earth we acquire 4ss tokens anymore... this weekend's faction feud had none in the milestone for solo or faction - and only two on the limited time tour.

Other than getting lucky in showdown store where are we supposed to be getting these going forward? Or should we expect them to suddenly become a paid loot special? Only being able to get 10 of them in the same class in prizewall bundle per month isn't ideal when you need 40 of them to take someone from 4sg to 5sb.

How can anyone compete in the new 5ss meta when it's impossible to get the tokens to even get a 5sb?
