Bucket hoarding is a slow process. There's no fast way to do it. However,

If you're hardworking you can get at least 200+ buckets from the daily quests alone and anything is is via weekly, montly and expeditions. Around 6 buckets per day is the usaul rate for dailies unless you do the World 2 quests and/or additional dailies which is more annoying to doo.

EO though....the best way to do it is to take it easy. 1-5, 2-5 and 3-5 can almost be done without using a single bucket as you don't really need to deploy heavy ships (unless you're using BB for 2-5). For 1-5, you can just switch the BBV/CVL around if they're damaged and repair them later. 3-5 depends on if you're going south (light fleet) or north route.

4-5 and 5-5 are the problematic one due to all the heavy ships we're going to be using. At this point....it's up to you if you wanted to use a bucket or not. Remember, you have a month to clear the EO.
