100% yes.
Which is why the overlap of crests between tracks will always be dumb.
Upgrading Hero to 6/6 will never be worth it outside of specific overtuned Raid Items you know you won’t have access to a Mythic version of (not YOU you, just, anyone who isn’t a Mythic Raider).
That’s wasted Crests that could have gone into literally just BiS minus 3 ilvl. That’s always going to be better for general gearing. Most people aren’t going to have a weird Mythic Raid loot funnel situation going on to make that a questionable choice.
And as a bit more of a tangent: Champ Track using THREE types of crests is insane. Under the current system, it should 100% just stop at 6/6 instead of reaching into 8/8 with Runed Crests. Champ Track is STILL equal to Hero Track outside of those specific Raid items for non-mythic raiders, because people are generally willing to blow Runed crests but NOT Gilded, because Gilded is reserved for Crafting.
Edit: I suppose I’m saying this from the perspective of someone not getting Gilded crests en masse early on. If you are, the time gate on crafting leaves you with a little wiggle room, but honestly still probably better to save the off-week of crests for upgrading actual myth track drops later. This wouldn’t apply to Delve-only players since they get the crests slower anyway though.
