I understand that delves are meant to be group oriented, but just in case anyone else thinks this idea exciting as well I thought I'd put it out there.
I REALLY want to see delve portals that only a single Trovian can enter. I don't have a preference on how I'd want the portals to be received (crafted, rng drop etc)but I honestly wish it was a thing. I also wish the royal blue colored name (viewable in old PVP) is a color that hasn't been used and I doubt the devs would add a new colored name to the game at this point but I for one think a colored name for the top 100-200 solo delves would be a fun new way to use the insane new power we have.
Devs, if you're looking for new ideas I really hope you adopt this one, a potential reward for solo delves could be a chance to fight a secret boss that can move, jump, and attack like a Trovian does. how cool would it be to fight a shadow Trovian that can swap classes and use ults just like you can... I challenge the devs to make a boss that's genuinely difficult to face, we have so much power in this game, it's a shame that nothing can really challenge us because we just team up to destroy it.
