Make somethng akin to EQ 1 world bosses where they drop good loot, but aren’t zegfests. Put them on a daily timer. The current dragons are too easy and zergy. Add mechanics to them and make it where they aren’t beatable without a chunk of thenserver coming together. Right now, they are mere shadows of what they could be. Even put one on random rare spawn timer.
Biggest thing, they must be hard and more dynamic then current world dragons found in zones.
