Latest training lessons were sold for 4.2 mln, but one before that for 5 mln, so even higher.
Before patch, which destroyed lancers and archers builds, training lessons were worth about 2.5 - 3 mln. Now they are worth more, which perfectly makes sense.
So, thank you chadz for destroying other people hard work just like that!
I'm pretty sure training lessons will go for at least 4 mln in future, there are still plenty of people who want to change their class/build. And if you only think about that, it's not that much money for complete reskill (with one click, you can change your useless archer/lancer to mighty 2h hero!). You just need to sell 3 unused/rarely used +3 items to get those lessons, and I'm pretty sure most old players has some rarely used items in their inventory. I know all my friends do have them.
One thing I don't like about those lessons - why can't we change our names using them!? :(.
It's just partial service then, you can completely change your class, but you have to stay with your old name :(.
