Dear Blizz,
Here are some QoL changes which I (no one but me) would love to see come to World of Warcraft:
1. Race/Class Combo unlocks: We all know you can write lore to make anything work, so do it.
2. BoA Flight Tome: After getting to 90 3 times back to back, I think it would be nice to sell a tome for 10k gold which allows a lvl 1 alt every riding skill up to 310%
3. Change all BoP items to BoA and allow us to send useful items to alts. It might encourage us to play them more. Plus, if they are not useful, we can vendor them anyway.
4. Change the number 16 on the default back pack to 28. It does not need to be swappable. Keep it hard coded, but change the number of slots from 16 to 28.
5. Cross faction mounts. We've been playing long enough, I say if we defeat another player in PvP, we get a chance to COPY their race specific mount into our usable list. So, if I beat an orc, I get a wolf mount. If I beat a Tauren, I get a kodo. They keep their mount, I just get a copy of it.
6. Scroll of town portal: We already have scroll of Recall for Scribes. I say we go one further and allow Mages to make Scroll of Teleport (Insert city here) and sell them.
7. Tri-Spec: Let's just make all 3 usable without having to unlearn one to learn the 3rd again.
8. PvP Combat Restrictions: When in combat, insert an invisible barrier which prevents flagged opponents from phasing while IN COMBAT. Once out of combat, they can line jump and phase out, but in combat, no abusing phase mechanics.
I'm sure there are more that others might like, but these are mine. Feel free to add your own below.
