Sorry if I’m reviving a dead thread, but I thought I would offer a data point / point-of-view from how an 80+ mil SP player thinks.
I just checked prices on Jita for a large skill injector, and it comes to 840 million. So - to capitalize on the benefit of this booster, I need to purchase 2.5 billion in large skill injectors. I then get a bonus of (500k - 150k) * 3 = 1,050,000 SP. (Remember - I would already get 150k from using a large skill injector normally, so I’m really only benefiting 350k SP per use, up to 3 uses.)
If I train optimally, I gain 2 million SP / month. If I train as sub-optimally as possible, I gain about 1.3 million a month.
So the key question I ask myself is, “Do I want to get 2-3 weeks worth of training, RIGHT NOW, in exchange for 2.5 billion ISK?”
The answer in my personal case is an easy “No.” There’s no skill or skill tree that I’m dying to access right now. Primarily because, as others have stated, with so many SP, I’ve pretty much trained into all the areas I’m interested in.
I don’t think there’s going to be as much of a problem as the OP was concerned about. It’s a neat perk, and I’m not complaining about it. It’s just that the math, in my own case, makes the booster a don’t-use proposition. I’m headed over to the market now to see what I can unload this bad-boy for…
EDIT: Yup - these things have flooded the market. I see no concern. Current price is about 60 million, and there’s even an opportunity for arbitrage on one unit as I write this.
