Uh, yes you do. Your whole entire point is that you want it to be fair to players who don’t do endgame content. The amount of time it takes matters little in this situation because you still want Open World players to get the higher crests somehow, even if it means grinding them.
Badly formatted. Also, that’s fine. But it’s not endgame content, therefore you won’t get endgame rewards. And as a quick thing, you may get worse loot than M+, Raid and PVP players, but you get far more mounts, cosmetics, pets etc than them.
Actually, it does matter, for reasons why I’ll explain below.
Again badly formatted. First of all, as people have already said to you, it’s open-world content. In WOW’s (or nearly any MMO’s) open world, gear DOES NOT MATTER. Sure it may make you feel more powerful when seeing all that extra damage you’re doing, but what is the point of that damage if you’re not going to use it for something?
The point of gear is that the better gear you have, the tougher challenges you can face within the game. But if you’re totally sticking to the open world, then the most difficult challenge you’ll face is the WB’s which can be taken down very easily if you’ve got a good amount of players with you regardless of what gear you have. It’s a simple truth that the open world is easy because there is simply nothing challenging there, and even if there is, a small group can almost easily do anything a solo player can’t do there no matter what gear you or your group has. It’s a simple jumping-off point when it comes to gear.
I despise BFA. It was worse than WOD in my eyes. And I only support two changes made in BFA (regarding systems). This is one of them. Constantly upgrading and progressing your gear which you’ll never use is an improvement.
TL;dr: Getting gear if you’re only playing in the open world is redundant and pointless, regardless of how fun you think it is.
