I spent less than an hour questing in the first part of the area, doing the quests of the first ranger, and gathered 112 simple extracts and 2 rare.
I was completely alone, not another soul around, which will most certainly won't be the case after U19 goes live.
If you take into account that with the current build you need 4 amber and 2 sapphire extracts per piece of armour, for a total of 24 amber and 12 sapphire, which means a grand total of 24x125+12x250=6K simple extracts (not counting any rares from gathering or deeds/quests), that is approximately 50 hours of flower picking ALONE. No idea how that will play with other players around.
I forgot to check if the Ithilien essence boxes are still for bartering and if yes for how many extracts, 'cause that will give incentive for everyone, regardless of the armour available and obtained to keep gathering extracts ad nauseam.
Personally I don't mind the 50 hours for the armour, but it would be nice to have flowers all over the area and not just in specific places, so that the players will disperse.
