From descriptions of battles against the Franks and Allemanni we know that ambushes were a favoured tactic by both sides. For example, The Battle of Strasburg had part of the Allemanni right wing hiding in a marsh.
The battles appeared to almost proceed to a set format. Both sides would form up, the Romans in at least two lines of infantry with the mounted generally on the wings. Both sides then moved towards each other and stopped at approximately javelin range. Missiles and insults/battle cries were then exchanged for awhile unit the signal for the general engagement was given by one side or often both (even the 'barbarians' had musical signals for the general advance).
The barbarians were characterised as either charging wildly as a mob, or moving steadily forward in 'dense columns'.
As long as the Romans could withstand the initial barbarian assault they would then generally gain the upper hand unless something else happened which may tip the balance in the barbarians favour, such as the nobles breaking through the first line at Strasburg or the Gothic horse suddenly appearing at Adrianopolis.
Even if the Romans did 'beat' the barbarians, it was often a bloody affair, such as the Battle of Ad Salices indicates.
Very few casualties were caused by missile fire, and the vast majority of casualties were caused when one army broke and the pursuers then literally mowing the routers down.
Most battles would last a number of hours, in the majority of cases until it became dark enough for one side to make a break for it hoping that the darkness would allow them to escape their pursuers.
From the descriptions it appears the barbarians tended to be in very deep formations, relying on constant movement and pressure and sheer weight of numbers to try and overwhelm their Roman counter-parts.
How you successfully model this with a set of wargame rules I leave to those who design such rules to figure out!
I share your view and that is how I would describe battles also for earlier periods. That is what I had in mind when I made my propositions of changes a while ago. I hope I am not too repetitive but from your description it comes to my mind that
1) Barbarians should have an advantage at impact
2) Cuneus formation (a very deep wedge) could be put into play with real gains in combat
3) If they did not disrupt the Romans, the Barbarians were in real trouble. That is why I think removing the skilled swordsmen capability is not the answer (maybe restricting it when the Romans are steady?).
I can't see a case for creating a rule of shield wall as I see the main differences at impact, but I agree that Barbarians and Romans fought in such a different way that they should be classified differently. Now Romans are drilled Gauls sometimes with better armour and that does not feel right.
