So I had to agree, like in that joke: "After 250,000,456 attempts, the server agreed that its password was Mao Zedong."
It's a shame...
P.S. I plan my development path even before the battle, studying the skill tree and documentation. But sometimes, you need a specific skill, like magic from the Sanctuary, and it only becomes available at level 12 and beyond.
At that point, all your development goes down the drain.
