Oh you definitely should, it's alot of fun and more updates for factions like Skaven and Undead are on the way.
Just expect to get into some bad moments with more powerful warbands and even getting robbed of your stuff. All apart of the Damned city experience.
As for my other two warbands.
The Baron's Blades: focus on swordsmen and crossbows. My first two missions were only won thanks to my captain, Baron Klatz. Both times my henchmen were taken out and only the Baron pulled off a victory by killing their captain and the then the next fight by winning three-on-one.
Azyrheim Auxiliaries: elite two-handed weapon warband in gold colors. First fight was a crushing victory followed by a crushing defeat as it was five against two and they had plate armor. So my captain, Lord Stratos Skyslash and Knight Dreadlight were both unable to fight the next battle with the lord out for three battles.
I had to disband the Knight and hire a new recruit who'd have to solo three missions without getting injured. By God-king Sigmar he did it even with four to one odds and managing to kill three of them.
Now I have three holy soldiers with good armor and wielding deadly comet halberds. They've yet to lose or get injured again and are going from win to win.
Only the Faithful!
