I definitely would like to see some new items. One area that seems to be under represented for humans and elves is the earring slot. I know the HCI earrings, and SDI earrings are out there but depending on the shard you play on, can be hard to obtain and if you can find them, extremely expensive. Something that maybe has some useful mods for a mage (one item) and a warrior (second item). I am all for some cool house deco items as well. I am partial to more of the classic art (original art items such as flash, candles, scrolls, open books, etc.) and less some of the new art items personally.
As someone who did not play from roughly 2015 thru 2023 though, the reintroduction of items that were previously available would be nice as well. Items like Paladin Bracers, SSI Epps, HCI Earrings, Archlich robe, etc. are all very solid items that if available can really change how you build a suit or character. Unfortunately on most shards, other than Atlantic, finding even one of these items that someone is willing to sell it almost impossible. So being able to obtain them another way would be nice.
Outside of rewards, something other than a tokuno style event would be nice. I remember the monster invasions of old. Something that progressively got harder, similar to a champion spawn, with an eventual 'boss' or 'general' could be fun. It would definitely be cool if the amount of enemies in the area was directly related to the number of playable characters in the invasion area. The amount of spawn killed would have not effect on the amount of points earned (see next paragraph). This would instead allow smaller and less populated shards the ability to fight at the same difficulty level as more populated shards. Having it tie into a story line gives a purpose for those who enjoy a bit more of the RP side of things as well.
Having some type of point system that does not require the turn in of items but grants based on participation similar to void pool would be cool. The points would then be used to claim items from an NPC that is only available during the event. I know some people would not necessarily be as big of a fan of this type of system due to the inability to 'sell' the points similar to how people sold pirate hats the last event. I could go either way though.
