Thanks for the clarification, i think most of us agree here that we as kinda regular pvp players are scared of even the thought of legendaries being huntable. Your suggestion sounds way better this way to be honest and I'd totally be down for it. I still don't really see a way to implement it as a "hunting" thing on its own, but perhaps it could be a really grindy thing connected to hunting - like catch x and y pokemon with minimum 150 ivs, catch a shiny of that pokemon or smthing like that and in the end you'll get the item to make your legendary shiny. If not going as far as shiny legendaries, I'd still totally support something that'd make hunting more rewarding, because now the only things we have are the bcc and fcc every month + the event hunting contests - which are luck dependant and lots of players take part in it. So adding something to freshen up "pve hunting" could be beneficial.
You've got a +1 from me ^^
