Thanks Dazo. The most I was thinking of doing on the Western Front was maxing Entente Trench Tech at 4, instead of 5. I didn't know that about the Austro-Hungarian trenches so they sound like Trench Tech 5 too. What about Russian and Ottoman trenches? Maybe they could be 4 as well?
"Austrians believed their trenches to be impregnable. They had dug five trench lines in some places, 8 meters deep, covered with logs and full of supplies and weapons. The soldiers lived comfortably with facilities just behind the front like bakeries. [...] Brussilov attacks on 4th June. He makes fire walls with his artillery and trap Austrians in their deep shelters where they can only die or surrender."

What I know about others:
As for OE ones it's more of a mixed bag due to various geographical theaters (desert, mountain and such). They usually dig well though their trenches arn't as elaborated as german ones but it's mostly due to a lack of equipment. You still have german assistance all over the place for officer and technical training.
If you want to "dig" more about that, look at Kut el Amara siege or the trenches them made around Gallipoli which were no joke (Liman von Sanders in command with mostly german officers) while those in Palestine were quite bad. In the Caucasus they relied more on mountains and difficult terrain than state of the art trenches.
Russian ones are even more disparate because of front length, various terrain, appalling living conditions and lack of supplies. Plus, like French, russian soldiers were overall more fitted for offensive than defensive. They had many hands to dig but technical mastery was lacking and many officers just didn't care.
Some positions were still quite hard to crack like Riga which Germans had to flank and attack with new tactics even at the end of the war.
In the end, trench techniques were more or less the same but Germans had more ressources and will to implement them fully.
That said, feel free to experiment with the editor ;) .
