SoftServe is still very useful to me because:
1. I use Citi DCB as my main CC; if there are CB offers on other cards like random Discover offers, I switch to it with ease; btw, I also registered with DiscoverIT double CB offer that started June 1 so that also gives me 2% CB for the next 12 statements;
2. I can still switch to other CCs, not just amex, if I need to meet min spend.
