Some people do leave the game over changes like this. Hope you aren't one of them.
This is sort of my point. Why make respecs so incredibly difficult to buy that people feel helpless in trying to fix their build, and eventually quit? It shouldn't be free, I agree. But it also shouldn't be so prohibitively expensive that people consider throwing away five hundred hours of playtime to avoid having to pay the cost of it.
I think you should easily be able to make what it costs to respec in the timespan of a single generation between selling a loom point and the gold you made for that gen. Anything over that price, in my opinion, is unreasonable of the devs. I also think it's unreasonable to come up with a ton of options for people who need a respec to "adapt" and piss on their invested time, instead of just appealing to the devs to implement a system that takes them very little time, and makes things more convenient and enjoyable for everyone.
P.S. 500 hours of playtime is what you throw away if you respec at 1/2 xp cost from level 36. And this is with the unrealistic assumption that you had a 5x all the way from 35 to 36. At 1x, it's like 2600 hours.
