I think it would be nice if the chain for gathering continued from node to node instead of applying to each node individually.

So you hit your first item, miss, then hit the last two items in a node and get chain 1, go to the next node and hit the first item and its now chain 2, I think this would not be overly unbalanced and allow gatherers to chain a bit more often.

I also think that GP recovery should be between 1.5 to 2 times as fast as it is now, or make the GP you get from gear/ add to gear via materia be more substantial than it is now.
