Is it just me or are the Triarii unrealistically tough to fight?

[econ21]

The proposed triari stats look good to me, Qwerty! Still better than principes but less godlike.

I may have got it wrong, but do the stats leave the early triarii still marginally better than late triarii? It would be unfortunate for gameplay reasons if that were true - nobody likes an upgrade that turns out to be a downgrade. An ahistorical fudge factor for the late triarii may be justified (rather like what CA did in MTW to make the feudal=>chivalric upgrade pay off for knights and MAA).
