It's a great site. The skill planner has come a long way - it's an awesome tool. The speed at which he keeps it up to date - adds features - yes, definitely something to be commended.
9 in Driver Coils though?
That's 9k SP that can be better spent...anywhere...on any build. Outside of somebody that's leveling, is poor, and hates travel times - something that they'll regret later when they respec out of it...or...outside of somebody that's a Tour ***** - it's probably the worst skill on the list. It definitely needs some love to be competitive in the least with any skill on their - space or any ground career...
