I don't like this idea because it generalizes species too much. And can also reduce roleplay, even if you may think that it enhances it.
Heres a few things to think about.
1. While orc war machines are common in things like lotro and WoW, I myself do not enjoy carrying over so many fantasy stereotypes. I mean sure, maybe orcs have war machines more often, but what if I roleplay as a human from a tribe of orcs? Why should I not get these machines and powers? Or, what if I roleplay as a savage tribe of humans that often go pillaging and raiding? It is likely that these humans might even have better machines than orcs, why do they not get them?
2. If you add a mechanic like this, orcs are going to be too much of a "special" race. If they get war machines, why don't I get the dagger that my character has? I don't mind, as I roleplay having the dagger, and will often use a piece of flint, or a sword to represent it. Now I'll be fair and say that it is much harder to roleplay a war machine than a dagger, but to be honest I don't think we should add mechanics like this, as the server has been just fine without them, and it will just complicate things.
That is fair. Though if something like a war machine pluggin/mod (yes i know mods will never be added, but this is an idea suggestion thread after all) perhaps it could be expanded to all races.
Naga with war boats, as well as Maiar.
Humans, dwarves, and orcs with similar war machines, but perhaps each being slightly different.
Yanar and Vespids with some organic war machine.
Agni with some sort of fire monster thing. Or a fire charge thrower.
Vampires...well, I suppose they should have the same as humans.
Other races that I know I am forgetting, but I cannot think of anything for them.
The only issue with all this is that what limits who can use what? A human could be taught how to use a Nagan war boat, or at least I would hope so.
I do not support the common cause of people trying to isolate every single race by giving them so many powers to make them stand out. It is not uncommon for elves, humans, and dwarves to live together, so I don't see their technology being that different. Same goes for orcs.
Why would vespids have war machines? There are bugs, living in large hives. Don't quote me on this because I'm no vespid expert, but I don't believe they are as technologically developed as other races either.
Why would Yanar have war machines? They are an incredibly peaceful race. I suppose it's possible that some might be fighters or go to war, but it would be an extreme minority, and I doubt there has been or ever will be an army of Yanar. If there any fighters, it's likely one or two Yanar that are assisting others.
Why would Maiar have war boats? They would move faster by swimming than they would with a boat. Maiar are essentially either savage fish or water elemental people, or just kind of humanoid beings that live underwater. They would have no use for boats, that's a contraption that was designed for beings like humans that can't live underwater or move at such speeds.
Sorry to seem like i'm just putting down the idea, but I think it was a tad ill-thought out. A nice basis, but ideas need to be thought through more before they are posted.
My final thoughts:
If someone wants to RP having superior war machines as orcs, that's fine with me. They can build them with blocks, and perhaps make use of the cannons plugin to do stuff like that. However I think it's a silly idea to make a war machines plugin just for orcs, or any other race, for that matter.
