CCP chose to go with SP injectors to catch up and expert systems to fill gaps for new players until they’re skilled.
What we could have is more SP rewarding for in space activities like other MMO levelling. They have it that way to encourage/reward playing the game, not this lazy background skilling stuff.
Also review the skills as many can be removed imo as they’re out of date, jump clones for a start can go imo.
See my topics on it here Suggestion for changes to jump clones and Change the rewarding system to reward logged in activity rather than logged out or idleness.
