Walkthrough tips, Discussion of Campaigns [Heroes 5]

I finished it!!!!!!!
The last campaign is nonsense, like it was made by a half-drunk mapmaker.
You can play it with your eyes closed!!!!!!!!!!!!!!!!!!!!!

I still don't understand what the garrisons on the maps are for??????????? I always just ran through the portal :-) I especially liked it with Raileigh!!!!!!!!
And I didn't understand why they didn't translate the dialogue with Raileigh??????????
And the plot is nonsense...The Archmages are *censored* unfinished... Especially Tieru...
Does anyone know what happened to the Elven king? How did he die?
