Well simple depending on the person, but from my perspective, it's fairly simple.
First suggestion:
My first suggestion is for sk to create a falling shimmering white or whatever color feather aura. The feathers do not have to be very impressionable, just big enough so that people wont mistaken the feathers for chicken feathers. More like an eagle feather. Having some other kind of aura like a shimmering trail of lights or a foreboding clout dark trail for a darker version or even a phoenix version of flame feather this way there can be many variations. The point of this aura is to highlight the Valkyrie set or the fallen Valkyrie set or even the heavenly iron armor. For the heavenly iron armor, it could have a sort of blessed aura where it would be opposite of the curse aura. The aura could just be a ray of light shining from above the head of the character like a miracle. Well i can't think of an aura that would fit the word miracle lol, but i'm sure the developers will do some research and come up with something. I feel these angelic/demonic armor sets should get some publicity sense they like there getting very little attention cosmetic wise cause they have a good look in my opinion.
This is a stretch from the first suggestion, so something like a 1.5 sort of suggestion. I was thinking of an aura for the chaos set lol, and i know we already have a chaos aura, but i feel the red shouldn't be the only color for that aura. So how about an alternative color for the aura like black and red, red and blue, or some color that oppose each other like black and white. I feel that would be more chaotic for two things that oppose each other color wise would form together to create the chaos aura.
Second suggestion:
My second suggestion is for the chat bar to still be visible while the loading screen is on. I only suggest this, because i have seen that players during loading can chat and still type for other players to see. So i think making it more convenient for players to be able to chat with each other while loading instead of waiting until full load to chat is better communications for each other. This way, if one player has a long load, he can still talk with players already loaded and say what is happening from his screen. Well, it's not a very important add on, but i feel for convenient sake, it's a worthwhile suggestion.
Well these are my two suggestions, Discuss! In a formal not too criticizing manner. So no "this suggestion suck" and that's it.
Feather aura itself is useful outside of just valkyrie wings, so I'm all for it. You could probably reskin love aura with feathers instead of hearts and remove the pink swirly bit. If you're feeling extra have the feathers sit on the ground for a bit like sprinkle aura.
These could come in various colors... Prismatic, divine, shadow, regal, toasty, cool, etc. Would be a fun new aura!
A different chaos aura, eh, maybe. Perhaps a "conflict aura" with two colors that are opposite of each other (i.e., having a yellow personal color would get you a purple "secondary", and with red you'd get green, etc..). This sort of aura would be great for those sets where you have a personal color that clashes with the main color itself, so you could play into that role with the aura.
Chat bar thing is a good one as well, however it might be good to just have the entire HUD overlay over the loading screen. I mean, you can press the hotkeys to open it up, so it's not impossible, so having everything there and ready for you would be helpful for long loaders.
