Is that because by then they were using actual soldiers, instead of cheap peasant conscripts? What about later on, how bad would Hadrian or Antoninus Pius (yes, I know, no major battles) have been burnt by that loss?
In part, yes, the loss was more severe due to the Legions being better trained and equipped by that time - and a mostly volunteer force, which is harder to replenish. Hadrian and Antoninus Pius would have been similarly hard-hit. It’s also harder to muster and deploy a force across an entire continent (and, especially, to manage those supply lines and borders simultanously) than in the days of the mid-Republic, when you could just look around the neighboring villages and drag off whatever young men you needed to muster another army to die to Hannibal.
As far as my memory goes, the only time Romans lost comparable forces during the period of the Principate was during their gruesome civil wars - namely, the Year of Four Emperors and Year of Five Emperors.
Well, that’s also the thing - taxes in the most vicious wars of the mid-Republic were very ‘ad hoc’. For the mid-Republic, it was something to the tune of “Wow, we need money, tell everyone in the city that we’re taking their earrings to sell for the Survival Of The Republic”, while gathering taxes across an entire Empire without losing 90% of it to corruption and general lawlessness is much more difficult - and, considering the very makeshift tax collection standards of the Empire, difficult to scale up. It has to be more ‘structured’ to ensure that any of the money gets to the central government, and the Empire was generally hesitant about imposing new standardized taxes outside of the city of Rome itself.
Rather than sources of recruits being concentrated, you’d also have to deal with Roman coloniae being scattered throughout the Empire, meaning gathering even just a handful of men from each one would mean a whole lot of shipping new recruits to where they needed to go - bearable when there’s no immediate crisis, difficult when you need a bunch of soldiers to replenish the ranks at once.
That being said, there was considerably more money available for the Legions - it was, in fact, by far the greatest expense of the Roman government. But as mentioned, the Legions were also considerably more expensive - getting all the supply depots and guarded wagon trains to reach every frontier of the Empire is no cheap task!

Hmm. Shouldn’t more territory also mean more recruits (and more taxes to equip and train them), though?
