That's the problem. The dragons take too darned long to make their appearance that the only people who will be bothered to camp are those with bots and threats of bans won't deter them because you'd be losing your sanity waiting properly for it to appear.
Even when everyone has their old gaiters replaced by the rare/ex version that still won't stop the bots from making regular appearances. As we have witnessed with Vyrtra and Jormungand, none of those dragons are ever wandering alive, there's always a bot camping them and they don't drop anything of seriously high value other than AF/relic upgrade materials, dragon-based materials, and a huge wad of gil.
