My material loading is level 20, it is fully upgraded. Why in diamond repositori with 49 unit mortar infantry in diamonds takes 42 minutes to collect but other player only take 32 minutes.
The operator also gives gathering speed or capacity, along with the activation boosters and executive status.Also keep in mind that some base layouts offer gathering speed. Last but not the least, we have the DARKLABS every 2 weeks , and there you can increase your gathering speed temporary by hitting the locations and collecting the bonuses.Hope this helps
