I couldn’t work this out at first. These infusion changes didn’t seem to be really solving the problems the game had, such as player having to choose between AR infusions for fractal or stat infusions for PvE/WvW. Then I realised what this is all about.
This is an infusion gear grind. Collect lots of little infusions. Spend money. Spend tokens. Use crafting skills. Get better infusions. Repeat ad infinitum. This has the appearance of a plain straightforward gear grind and it will probably solve no existing game problems.
