Yeah, you can provide item/pet sketches and ideas to toss up for fun and suggest how features work.
No guarantees that it will be in-game, but it's good to get the brainstorming going.
That's awesome, happy for your interest there will be a form to fill out for alpha I'll only be selecting 100-ish people to test the site out. Everything will be wiped though and it's mainly to test features out and make sure everything is working the way it is. I'll keep you in mind for sure!
Just sketching a pet idea, may not actually be in-game.
