Guild missions have been a part of the game that has been neglected for several years. In MMOs, people look for social connections with others who have similar interests. Early on in the game's history, guild missions were good opportunities for bonding and making meaningful friendships by making guildies gather weekly for a communal event, incentivising members to gather socially and get to know each other better. However, as most guilds these days have quickly reached max-level, and more efficient meta events have sprouted up throughout the years, guild missions have become irrelevant for many as the individual rewards for doing them are lackluster: you don't get much currency from them, and the useful items you can buy with guild commendations are limited.
So, how can we fix this?
I believe the best way is to expand the exchange options available using guild commendations.
For example, we could have more weapon and armor skins that get updated yearly or every once in a while for the fashionistas.
In terms of gear, the guild weaponsmith and armorer could also offer stat selectable exotic weapons and armor pieces with core and expansion stats, going beyond just backpieces.
Guild commendation traders could also offer stat selectable ascended accessories, rings, and amulets too, solving an issue with gearing alt characters, as laurel vendor traders only offer core stats, and obtaining stat selectable trinkets efficiently is gated behind living world seasons.
For people who have fully geared their character, we could also have more gold oriented improvements to give them incentives to still do guild missions, like adding a permanent trophy shipment option.
It would also be an insane quality of life improvement if you could obtain provisioner tokens and mystic clovers through the guild commendation trader as a way to obtain these time gated materials, thus incentivising people to do guild missions more.
Even if only one or two things from the list get added, it would be super beneficial for everyone.
