I have played 500 hours since the last update. I’ll give a brief overview on what usually happens.
First of all, yes grimgor is usually very aggressive in the early game and takes a lot of land. However in doing this he gains a bunch of powerful enemies such as the dwarfs, clan mors/eshin who will military ally and crush him by the mid game.
Vampires vs empire can go one of two ways. From my experience both vampire counts are very aggressive but only manny is able to back it up, vlad will over expand and get destroyed quite fast. I would say it’s around a 95% chance for the empire to win, the only time the vampires have won is if they bumrush reikland early on.
High elves vs dark elves happens the same time every single time. Morathi is very aggressive, she takes over half of ulthuan, Tyrion joins the war and destroys the dark elves, morathi will usually confed with malekith and then Tyrion recks him too.
Bretonnia are very passive until the late game, they don’t do much apart from fight norsca and a few minor factions, like mousillion. At the end game they are usually at around strength rank 5.
Lizardmen ar also very passive in my experience only the last defenders have a chance of becoming a major power, itza and lord mazamundi just usually fight chaos and skaven all game.
Thanks for reading my blog, hopefully this helps you out. I don’t think the ordertide is as bad as it once was but tyrion is definitely the worst out of the lot
