The respec is behind a :effort: paywall.

You need to have finished act1 before having access to it, and so it's a great tool for people who realise they have gimped their build with bad choices but like what they actually have done with their roleplaying or just don't have time to reroll and begin the game again. Or, you know, know they would lose motivation to play if thye do.

Then if you want to abuse it you need to go back there, make new characters and spend time abusing it. It has a high 'effort' needed to abuse, and when it comes down to it, it's OK if people want to spend a lot of time to abuse a game. It's part of the game, and it's something most people just won't do because it's, for most, not a fun thing to do. For the people it's fun to....well, they can do it. It's good for them.

It's also very good for people who get stuck at a wall and realise they /need/ a respec or they have to stop playing.

Or, as people say, for experimentation.
