So it sounds like they just adjusted that artifact trait/relic combo to account for the extra traits you can pile on top. I'll have to draw conclusions closer to release when they've fleshed out the artifacts better, but I do see your point.
2T19/4T20 does seem like a great combo. That'd make First Blood blade dances generate, what... ~30 fury? In addition to Felblade and DBlades. And that's not even talking about AOTHG. Seems like any kind of fury issues would be gone for good with that setup. Then having DOG/COF/Meta relics going on top of that for 2min metas...
I'll um... I'll be right back.. lol
