Well done PA, lets drop event that was made for low population regions into NA/EU where bosses spawn with 20% HP because player base is superior to regions you made this event for. Thanks for accounting our region when making new events!

They really need to have a "dim tree will spawn in 10 minutes" notice.  The field bosses are all dead before anyone gets there, and i'm not going to park a Boss alt at every field boss, that is just a waste of time.

All 4 bosses spawn at the same location outside the central city of the game at a set time each day. Seems very uncomplicated and doable for every1 since the time varies to allow ppl that work different times to at least participate some of the days.

Try reading the event info next time.

There's an current event where Red Nose, Bheg, Mudster and Dim Tree all spawn in less than 5 minutes, at fixed hours, northwest of Heidel.

But as Potato mentioned, by the time you manage to land your first hit on them, they can already be at 20% HP. It happened to me, I saw Dim Tree being summoned, I stood near him while attacking without rest, and when it became targetable and I landed my first hit it was already under 20% HP. 

Honestly I didn't read the event much past, Field bosses, and Must kill field bosses.  It got filed under, content I most likely will never do.

That being said, my point stands, that Field bosses need a set spawn timer like the world bosses do, or at least a better notification system with a warning like "The hills around Western Guard camp are stirring with Comotion, it seems as if Red Nose's army is prepairing for battle" which would then indicate that Red Nose would spawn in 10 minutes.  As it stands (ignoring this event) if you do not have an alt at each Field boss, the Field boss is dead before you can even run from the nearest city a lot of times.

There is 15min channel swap cd so the boss train actually take up to 2 hours to clean out all channels depending on the time of the day.

I usually manage to get 4-7 kills on a boss per spawn when I participate.

Yet another flaw with Field bosses, the only way to experience the content is to join a 3rd party program, otherwise it's dead content.   

I don't see it as a flaw, ever since Internet has started being a thing, there has been third party volunteers adding their contribution to online games, being it through tutorials, online maps (Everquest) or mods. Not only it adds to the experience but this is really a common matter that should be seen as normal to any gamer.

Furthermore, before boss discord was a popular thing, BDO players used to collaborate ingame in order to coordinate boss trains and it worked.

Hmh what? This event DOES NOT EXIST.

These are not real field bosses. 

People came because they thought so, but ... these bosses don't give you anything, just 20 hunters seals:
