They need to either update them to the degree that 90% of the builds aren't simply a "push this button to gimp the **** out of yourself" option or just pull them.
Literally the only purpose they serve right now is helping new players not bounce immediately off of the game. However it's basically doing that by tricking them into thinking those builds are decent, and that it isn't pretty much necessary to either (1) do a lot of trial and error yourself or (2) doing a ton of research outside the game. They are kicking medium term retention in the teeth to help with "first five minutes of playing" retention. Wouldn't it be better for the preselected paths to help with both?
And yes, it would be some work to update them. But it wouldn't be That much work. It's not like we are asking for new graphics assets or something. We are talking at most a month of work for someone. Strimtom or someone else really knowledgeable could probably improve all of them in a few afternoons.
I also highly don't buy the argument that players wouldn't learn anything if the paths were good because they wouldn't understand how they work. Does being tricked into playing a build that is actively bad really make it easier to learn the game than no guidance at all? Degimp them or ditch them.
