+ A large number of early-game archers – good for clearing the territory.
+ 5 levels of Guild Master + library
+ Quite good starting heroes
+ Relatively cheap construction of giant dwellings
+ Quite strong units of levels 4-7
Disadvantages:
- The castle itself is expensive, and building Titans is extremely costly.
- Weak units of levels 1 and 2.
I haven't found any more disadvantages yet, but I think there will be some.
