New specific tutorials will come later.
I agree the game has become much more complex now that we have more tools to design AIs :/
Should I remove tools? I don't think it's the right solution.
I think it's mainly due to a more dense UI.
That's why in Alpha 8, I'll work on the target system refactoring, adding target presets (e.g. "Closest Threatening Enemy" AKA "Closest AttackingSelf Enemy", "Ally in distress" AKA Closest 0-25%Shield Attacked Ally, etc).
You will still have the option to go deeper and create your own target setups like today.
They will be reusable easily, you won't have to select the target type, selector and all the filters, just reuse your target setup.
It will add more menus but if you don't want to "go deeper", you can stay on the upper layer and see a much less cluttered UI.
