I'm not sure if this has been brought up before, but here goes:
Which is the worst faction in R:TW ?
For me it would have to be Britain. There doesn't seem to be anything that they do well and they just feel really disapointing to play. My list of grievances:
No foot archers
No horse cavalry
No siege equipment
Minor city maximum settlement level
No heavy infantry
Weak navy
Only 1 mercanery unit on homeland (that they can recruit anyway)
All this faction seems to do is chariots and to be honest, they're nothing special. They seem to totally rely on strategy and generalship to get anywhere. I also find myself using lots of mercs just to get by - especially Barbarian cavalry. The loss of Belgica really could finish the Britains off since no barbarian cavalry mercs can be recruited in Britain.
