heritage armor can be used only by the race, the warfront can be used by everyone.
heritage armor have a big chunk of lore, warfront set don't have it
heritage armor have higher quality, warfront only the elite version.
the warfront is both horde and alliance themed, not just orc/human, like i said ther eis no problem tot hen get later, but they should get too and the warfront is not rly a replacement. .
Think about it this way. You are completely new to the game, or returning with no insight into the inner workings of the game and transmog or whatever.
You are shown a dwarf in full Heritage armor, a human in the Elite warfront plate set and a Forsaken in the elite Warfront mail set. Would you be able to instantly distinguish the heritage armor from the elite warfront armor?
I am not trying to argue that they are the same thing, Heritage armor is definitely a different entity from the Warfront sets, but it is still about the same level of visual identity being given to a specific race, and giving a race both of those in short succession would feel quite bad for, say, the troll players of WoW, or the Pandaren.
The more I think about it, if Tyrande wanted to cripple the Horde taking over Mulgore would be devastating. Doesn’t it supply most of the grain and fresh water to the Horde? Maybe since it’s such fertile land Malfurion could plant another world tree there.
Her Forsaken had really close bonds with some of the Tauren. Mainly the Grimtotem when they were still there, but the Tauren as a whole were the ones to take the Forsaken in and actually try and help them before all others did. The pools of vision (or whatever they're called) in TB are completely populated with Forsaken. Sylvanas specifically reminded Baine of that in BtS to get him back into line. So I could imagine at least a small group being pro-Sylvanas, although I don't think they will be very loud about it, unless we actually still see a coup in TB maybe.
Because regardless of other races being able to use it, it is still a high-quality set made with post-Legion levels of detail that is styled after the aesthetics of a specific race.
It is not the same as a Heritage set because of the fact that it can be used by a different race. But it is still more or less the same thing when it comes to the surface level "Race-specific high-quality armor set"
