This is a ridiculous statement.
DT has thousands of tutorials across every major DCC software package.
Nor to mention they are now under pluralsight, which is thousands more tutorials on programming.
They are also the most pirated digital tutorial site on the web. If they sucked so bad, why would they be?
For ue4, yes there are only two tutorials right now, so don’t get it just for that. Give it two months.
If you want to learn other stuff in the meanwhile, absolutely worth it. annually is the way to go.
