As someone who has mained a crafter in SWG since about 2005, this was a fun thread to read! Agree that SWG crafting is unlike any other out there, but that there are some improvements that could be made. Here are a few quick ideas (coming from someone who basically has 6 elites deployed at all times, but doesn't actually craft or sell anything, lol):
Add a new Architect schematic for something like 'Solar Powered Array' that is an optional sub-component of every harvester. This would take a large amount of a resource, say Solar Energy, up front, but turns it into a self-powered harvester
Similarly, find a way to add a homing beacon an an optional sub-component to harvesters so someone can ITV directly to them if on the same planet. Otherwise I agree that the Hoth / G9 Rigger ITV's are easy enough to use to get to your harvs, but can take time to get enough of.
I like the if maintenance goes below 0 then just deduct from cash or bank idea. Summing up those three ideas would make harvesting resources a much easier task to manage on a daily basis AND gives architects something new to build.
