>>46751578Are you sure about that being true in ruby/sapphire specifically, not emerald? I could've sworn there was an area you couldn't access until post E4 because one of those elite trainers would block your access and tell you to come back when you're skilled enough.
Regardless, it's a fairly obscure location that most people wouldn't even think to find after getting the waterfall HM. Unless they already know about Bagon being there, but only guidefags would even know that. For the majority of people, they only looked up where to get Bagon after fighting Drake's Shelgon/Salamence and wanting one for themselves. But of course that'd be post-E4 anyway.
