Is an extra pop per season (over a level 5 trainer) really worth that much money? And seriously, if you are not a division I team, why would you even bother?
I can answer this, from personal experience. It's because every piece of information about training (such as
(78242.1)) was about what a level 9/10 (in the old ranking system) trainer could do. It creates the expectation that that level of trainer is normal. I thought so too; I spent a long time trying to buy an elite trainer, before I realized I couldn't afford one, and before I read further and realized it wasn't worth the extra cost for a team of my level.
