I run an excell sheet and i keep log who had what pack and how many battles people partiicpated in people who participated in more battles get packs earlier but eventually everyone will get a pack assuming they participating in at least 4 battles overall.

Im thinking if we get merged it will be probably even worse as some servers have pay2win groups and some dont so some groups are going to go from regularly being 1-3 to 4-8 that wont help morale.
