Existing skill injectors will be marked as large injectors, while the new smaller skill injectors will hold a maximum of 100,000 points and offer smaller and smaller rewards to players with more skill points. The hope is that newer players can buy the bite-sized injector and start to catch up before moving on to larger purchases, thus ensuring that everyone can more quickly take part in the sprawling wars of backstabbing that make the game tick along.
