I believe that it would help the NPE if the Academy were longer, but not repetitive. Give it a graduated scale, so that players could learn the different modes and some of the finer points of the game. The bonuses that CCP has added for completing tutorial sections are a good start, particularly the bonus booster, though a little clarity on how to use it may be helpful to new players. If starting ISK were higher it would be helpful, but limiting farming is important so I like your idea of longer biomass time, or limiting the ability to transfer funds.

Introducing new players to Ambush, Domination and Skirmish would be good as it will allow them to get a feel for how the dynamics change in the battles. if progression through these modes happened over an extended Academy experience, then new players would also earn higher SP and ISK before graduation. I am also partial to the idea that academy graduation should include a respec, and perhaps bonus ISK. The respec would allow for a fix of misspent SP, and bonus ISK would cover wasted gear bought. A clear statement of the respec being an Academy gradation perk and not a common occurrence would be necessary.

I would agree that the Academy SHOULD be longer but at the same time what happens to them afterwords? They are still left with 500k ISK and 500k SP, which is pretty much the same thing ALL OVER AGAIN. Why not implement a graduating system where if you graduate from getting X amount of WP you gain SP, so thus in turn it allows players to have a "reward system" for them? Like if you hit level 1 of academy you get 1 million SP, Level 2 is (2- 3 million) and level 3 could be (3-5 million)? All the while you are still building on your 1 million ISK you have accumulated from character creation.
