option to sell multiple cards of reqs. E.g. Scout warthog x 22 as an example
-
daily and weekly challenges. Rewards could be tiered to the bronze, silver and gold, or make them specific e.g. Ghost pack for ghost challenges, etc.
-
community challenges (I saw this on plants vs zombies garden warfare 2) set the community to accumulate 10,000 firefight victories or something like that.
theres just a few little things to make it more rewarding to players rather than waiting to get that 10000 req points for gold packs and so on. Hope to hear any other thoughts
