They are noticeably more effective, whether that was tweaking the damage, HP value, etc...I can take a few more arrow hits than EA release (assuming that's what you meant by 'launch' for most of us here).
It's not their range that makes them OP, it's everything in addition (which are also top of the line) that makes them so. Remove the weird damage/effectiveness of polearms on mounts (another discussion), make horses easier to fell (too tanky), tweak their armor set, etc...HA with just range alone is barely effective - they don't aim as well or slow (cancelling often), take longer time to kill others, etc..., even if we give them 2 quivers.
Yes, Fians are stupidly OP - but to fix that, we should nerf them, not by make all other units' (armours) stronger. 'Cause now you have to deal with balancing all the other aspects of those updated troops for vs swords, vs blunts, vs polearms, vs throwing, vs cavs, and even vs map simulation/economy.
Ie. RBM also needed something like the posture thing to tone it down (though toggleable) and didn't mod any of the overworld systems from the consequence making the armoured troops 'OP/realistic'; which was needed to balance that aspect of it.
I'd rather nerf the bows at this stage before doing another buff pass on armour. Or give a wider variety of mid-tier bows for troop loadouts; reserve the noble bows for, you know, nobles.
For both bow/xbow, still think their range + accuracy aren't a close representation to RL (even in Warband). From what I understand, summarily, xbow's tradeoff was distance accuracy/speed less for power/close range accuracy (can hold at draw); bows, tradeoff was damage for distance/mobility reliability (consistency).
As much as I had also favoured WB's over BL's current, their range was still king too. I can just use the same smattering of shields in front with rows and rows of VMarksman and RXbows; without even needing cavs. It's not as easy to do that as effectively in BL.
It was also was harder/slower to accumulate the top-tier armoured troops, rarer occurrence of large battles, shields were weaker/'realistic', more foot shots, horses died more easily to them, bows less accurate at distance (and slower velocity/different trajectory too?), and felt like they couldn't aim as well near friendlies (imo).
With the AI logic being better/more efficient in BL, that plays into it as well.
