Technically it was "some evil gives speed to these creatures" but yeah the Uruks were tireless.but faster (I CAN prove that they were faster than even Aragorn Legolas and Gimli from the books)...
It wasn't the smithies of Gondor, elfhelm said ROHAN!! Besides Saruman was a student of Aule and therefore a cunning metallurgist, I'm sure he instructed his orcs how to make proper armour.You're telling me that generic Orc armour is better than the armour from the smithies of Gondor?
No but they are tireless (read the book before you disagree with that) and if they were unhealthy or susceptible to illness then they would die from their living conditions and food.No they don't. Uruks aren't as experienced, healthy, or fit.
True, except for making them weaker and burning their skin (that's what the big bright thing in the sky does to orcs)The dawn was only symbolic, it did very little to the Orcs
Only the west side of Osgiliath, the orcs still had the east side.Osgiliath was retaken.
Basically, considering that the Orcs did ultimately lose most battles, the odds can't have been that much in their favour if a relatively few number of reinforcements can seriously and significantly put the odds in the Men's favour.
If that were true the Free Peoples wouldn't be too concerned about having to destroy the Ring, they could have just hidden it away, but no they had to destroy it because whether Sauron got the Ring back or not he was going to win through numbers and LARGE armies, everyone knew this, hence the idea to destroy the Ring.
Why do you keep mentioning health?and probably not much better than Orcs in the other attributes - intelligence, training, tactics, health.
