The arrow markers for kegs at cobalt and food place for amber need to be improved drastically, it is hardly discernible at the start of the fight and even harder when there are mobs around it.
The newcomers dont know where to place the kegs and they end up all over the place, this greatly hinder the chances of pugs doing the event imo, and same thing goes for amber where you lose the buff and need to kill the carrier again, wich makes you lose even more time.
5 or 10 misplaced kegs arent a big deal when there are 40 kegs runners but 30 ppl losing the wurm atractant or the chance to get swallowed is a great deal when you have to res half of them and then kill the carrier again.
A Blue circle like the new area indicators would be good, that way it can be seen among the orange aoe indicators or just make the arrow bigger.
