On one hand, securing Kalimdor and Ashenvale for the Horde is an… okay idea. Even though the whole “let’s claim Ashenvale” is literally right out of Garrosh’s playbook, so Vaknosh is immediately suspicious that something is fuckity.
Murdering civilians in Astranaar, however, is not okay with him. Neither is killing a bunch of furbolg because they happen to have a camp to use. So that’s something he’s likely to avoid participating in. Killing night elf military is fine, it’s war after all.
Also, Malfurion Stormrage is a bastard and needs to die, so he’s not necessarily opposed to that idea.
In general, post-Teldrassil, Vaknosh and the Kor’kron Legion are pretty sour about the whole thing. To Vaknosh, he sees where this is going real quick. He’s served one tyrannical Warchief, was even party to some of his war crimes, and is pretty sure he sees another Horde leader who is going to have to be taken out eventually. The general mood of the Kor’kron Legion’s leadership is grim, but they’ll be fighting in the war – but more in something out of the way, where it’s purely soldiers vs soldiers rather than getting themselves mixed up in whatever tragedies Sylvanas wants to cause.
The Kor’kron Legion in general nowadays focuses more on being in service to the Horde, rather than in service to the Warchief. It’s one of the changes we’ve made as a guild as the lore has advanced. Nothing can completely absolve them of their past mistakes, but they can at least try to redeem their name by fighting worthwhile fights that’d either protect the Horde’s lands and people or at least not cause wholesale slaughter of Alliance civilians at their hands personally (though, of course, they’re guilty by association just like the rest of the Horde).
Vaknosh isn’t the High Warlord, but as their Warmaster, he’s sorta in charge of lots of… war things, so hopefully he can put his own personal touch on what sort of fighting the Kor’kron Legion does.
