i am sry to dissapoint you, but there is no difference between draco event and kailel, since u need to be on to get a reward from it. i prefer an event where ppl can farm for items, at least there is a chance to make them go farm other stuff except instances
ps1: you shouldn't care what ppl from other servers are doing, this is an older server and it already has the draco pots/qhp etc, so it doesn't really mater if there will be more.
ps2: with draco more epics will be on the market and is a good way to make outrageous prices drop, also event is the only way to get epics on server
