Yes, that is a nice thing! Would give us a true army that will not have to relly only on gadgets to win battles!
Well, I have some suggestions to bring Greatswords into line with their new looks. Heck, we do not need another unit not looking their part. After all, it is kind of not fair towards people to have to be versed in all rules aspects of all WHFB books to play a game without suffering simple suprises.
If I was up against Empire for the first time, and saw the greatswords, I would not bother to ask about their armour save since they could not be better than 5+ at most by looking at them. You must have great weapons visible for the unit to have greatweapons. I even belive there is a rule in the rulebook that a unit can have some different weapons mixed in, BUT the majority MUST have the correct weapon.
It must be obvious if the unit have spears, halberds etc... You must be able to see the standards and musician. As I get it, it is okay with some single oddity even in a tournament, but basically, it is about good sportsmanship to be clear about what kind of unit it is.
Now, if weapons are so important to represent on the unit, would not armour level be the same? I think it should. To me, it is important to know if the cavalry is barded or not, for example.
I think it is a bit like double standards. It is also about making it fair for both players. If you have to ask about every single unit to know what it has and donīt have, it sure will not make the game run faster.
For old grunts like many of us, mostly playing friends, it is not that big a deal, because each unit should be familiar. But for beginners this could be a bit bothersome, methinks. My sons would not be too impressed with the GS new plate. At least the old models did their best to look the part, the new plastics are not even trying.
Hence, I belive that it would be nicer, and more cool, to give the GS heavy armour, but also give them T4, just to show how badass hard these vets are.
