Actually I think the statistical data confirms what i say, quite well, lets see:
Why are these armies underperforming:
1 - “The results are due to randomness”:
If statistics are worth anything, than the conclusions we draw for the roman armies are among the best we can have with these data, as they have more representative samples (because they have many games played, their statistics are more reliable).
In the ranking by number of games played, the Late Rep. Roman is 2nd (630 games), Dominate Roman is 4th (549 games), Principate Romans is 7th (340 games), Mid Rep. Roman is 17th (279 games). So the statistics for these armies are less vulnerable to randomness than those of other armies.
2) Poorer / less experienced players are attracted to "traditional" Roman armies.
Indeed that could be one reason (and i believe it is). Next question would be why good/experienced players don’t play these armies. Possible answers, that I can imagine off, would be:
- Because the armies are not competitive and these players usually play to win tournaments, so they won’t choose them.
- Because if we compare the price per file of superior legionnaires with average pikes (so that the romans, keep the slight advantage it was mentioned earlier in the thread), you have 28 points for the romans against 24 for the phalanx, considering that the pikes will be at better or equal POA’s against almost any opponent and the legionnaires are vulnerable to a series of opponents, why would anyone choose the legion over the phalanx ? they like playing with it and don’t mind losing? they are good players and like the challenge? they are poor players and didn’t understood they’re army stinks

?
- Because Roman armies are many gamers first armies and then when they start to play better and understand the game, change to a more competitive army?
3) "Traditional" Roman armies are difficult to play well for poorer / less experienced players.
Perhaps, but there are others equally (or more) difficult armies for these players, I would say Seleucids can be one of these, and they don't show so bad in the ELO Ranking.
