The drops definitely change if you have the walker. Before getting the walker I received a regular 2 nectar at each collection, not enough to do continued crafting.. now I'm getting 4 to 5 and crafting with the boost. For the time being if boosted drops don't change.. I've doubled my collecting.
I haven't worked out the stats yet.. I'm just crafting ahead, but got stuck on 8th for 2days due to lack of nectar. I figured at that pace I wouldn't have days enough to finish, as last goals are very demanding as reported and then measured the pro and cons.
... It does say the walker boosts ALL drops needed: nectar, wood, ore, fur.. so should help in other collections and crafting, not only nectar.
... Another reason was on week days a 90 minute collection is difficult for me.. I would surely miss some.. plus this would continue for another 10 days! Now it's resolved.
... Last reason was having all the walkers in the set so far.. this one even if differently proposed would be missing.
