Supercell put out a statement on Reddit explaining how the new drop rates in clan wars work after the last update, comparing the old system to the new system. This is due to the large amount of complaints on Reddit that the trade token drops were actually "decreased."
Before the Update
10% chance of getting a trade token. Guaranteed trade token once every 15 matches. Technically, one could get 15 TTs in a row.
After the Update
A cycle that occurs every 8 War Bounties. The cycle is 5 Bonus Gold, 2 Trade Tokens, and 1 Gem drop, not in any specific order.
It doesn't feel that they are more frequent drops, and Supercell agrees. They are continuing to talk trade tokens for the next update, which is slated for late Jan/early Feb (another post by me going up soon).
