I have decided to split this into one whole forum as I realised these two things could overlap after talking with several RPers!
RPing in WoW is great and is heavily based on using the /e system where you write what your character does, how they react etc. Which is great, but there are basic emotes we all use every now and then and some emotes that we miss.
Looking at other games, there are some games that offer different types of sitting emotes; sitting on your knees, sitting with your legs crossed, sitting with your legs straight out, leaning back on your hands etc. Every single race in WoW has a different /sit emote (except for allied races), and sometimes, these don’t always fit the context neither does it fit the character very much, this goes for all the emotes (Read; night elf female /nod). More Racially friendly to each and every races culture would also perhaps be cool, adding the tauren spreading pollen or perhaps a Forsaken cracking their knuckles, two examples from the top of my head.
With Battle For Azeroth, we saw a ton of new NPCs and a lot more ambience effecs with the surrounding NPCs doing a lot of different stuff; carrying barrels/sacks, leaning against the wall, playing the guitar, bartending and such. These were all great, but they were kept only for the NPCs. These emotes should be looked to be added to the RP community as well, maybe if it does not work as an /emote, it could be implemented as a toy; bard playing a lute, sweeping the floor with a broom or carrying something. These are things that could create a lot more immersion as well as give the RP scene a better look than having to read and emote to every new player approaching what you are currently doing (e.g. carrying a barrel).
When we are on the topic of toys, toys have given a great new addition to the WoW RP community. With the Magic Pet Mirror, one can now actually take the form as a companion pet and that leads to a lot of creativity, but these players have to depend on the 10 minutes the toy gives and then spend every 5 minutes refreshing their Reflecting Prism. I have seen a lot of people requesting for this prism to last longer, such as 60 minutes or perhaps making it last until combat or such. There are plenty of ways to improve such a vivid and useful toy and item used by many.
To name a few others as well; the Highmountain Log lasting forever, placing down chairs, tables and banners would also be nice. There are immense things that I know not just the RP community would find enjoyable, but everyone! Toys are very fun to play around with and collect as well as emotes. We all use /dance every now and then, so why not add more options?
