100% absolutely. At first I was a little hung up on the whole covenant abilities and not being able to switch between them easily depending on the content I was doing. Slowly I've convinced myself that the difference won't be that significant because it wouldn't make sense. Ultimately I'm just going to pick whichever covenant fits the theme of my character and roll with it. I'm making my decision almost entirely on cosmetics and am going to disregard the abilities. They already said it's going to be tedious to switch covenants, so it doesn't make much sense to pick a covenant because X, Y or Z ability is OP at the beginning. WoW is clockwork, if something is broken and it's at the beginning of the expansion, you can bet your bottom dollar they'll come in with the nerf hammer and bash the ability apart.
I'd rather be happy with my decision because I enjoy the theme rather than forgo all personal interests for the sake of an ability that could get nerfed if it's too strong. Again, I don't think the abilities will be a significant increase in performance. I feel like most of the people acting like it'll be some horrible model are just blowing smoke out their ass considering there's enough enough data to determine one over the other. All I know is, that I won't be denied from a group based on my covenant ability. I'm too good of a player for someone to give a rats ass about not having some specific covenant ability that may possibly increase my performance by 1%.
Overall what I'm really excited about is gear becoming gear again. I absolutely hated how there were too many grind systems in BFA. I can tolerate one grind system, but when you start layering the game with multiple grinds, it starts to hinder alts. That's why I think 8.1 was the peak of BFA, not just because BoD was a great raid, but because there was only azerite grind. Prior to 8.1, you had to grind heart of azeroth rep on every alt if you wanted the extra 45 ilvl to your neck, but blizzard realized that was too tedious so they made the rep account wide. I was able to gear up all my alts through m+/BoD and it was an altoholics dream. Then 8.2 launched and essences were released. They were cool in use, but to obtain them was another story. I couldn't invest the effort to get r3 on all my alts and they suffered because of that. I wasn't about to grind 30k honor on each of my alts. So yea, I'm just glad I can go back to playing all 12 of my alts when SL releases.
I get it, people want to be able to switch freely, but don't start wildly speculating that the whole system will be a bust without any empirical evidence. I feel like that's a big issue with the world right now. People will take a lone fact and create a chain of speculations until they've convinced themselves that their hypothetical scenario will come to fruition.
