Some of you are really deep thinkers and planners.  Yet you may not realize this.

Every time you harvest you are likely to get an addition material or shards.  It is interesting to me that after a certain range you will be able to get one most of the time.  This does not mean you have to harvest the whole amount.

I would like to see the option to harvest a location for a certain amount that I list then my troops will return automatically.

For example, If I harvest a large resource location for all of its resources I will obtain only one item.  If I break it up into three or more visits I am likely to receive 3 or more items.  It is worth it for me to visit a location 3 times instead of 1 for the chance to get a few more items that I am looking for in order to craft items or fuse gems and shards that I am trying to obtain.
