That lack is irrelevant.

5 gather node, 5 shards. Use the Ward, you get +2 shards per attempt, for 3 shards per attempt. 3 * 5 = 15 shards for that node.
4 gather node, 1 extra yield, get 8 shards. Use the Ward, get +2 shards per attempt, for 4 shards per attempt. 4 * 4 = 16.

You get more shards on the +1 Yield than you do on the +1 Attempt nodes. That is even true when you add in the +2 Shard Ward skills.

I don't follow what you just said. The wards give 2x shards per swing regardless. If you have 1 extra gather attempt, the 5 gather nodes, you get 2 more shards than if it's 4 gather attempt. It doesn't matter if the node gives 2x or 1x.

The nodes with an extra shard will always give you 2x shard. It doesn't matter what node you use wards on (since they are all 4 attempt).
