Unfortunately, nobody on my server seems to be able to craft any tank mod/enh for the moment. Plenty of dps stuff, but nuthin' for the meat shields
Which server are you on and which side do you play? If you can't find any on one faction, try checking the other faction (I know I had to swap over to Empire to find someone that could make most of my Robust 27 unlettered mods until someone on Repub finally learned it). I know that most of the servers maintain a decent network of crafters that know what the others craft and, at least for Pot5 (my server), there is actually a consistently updated thread that has the various crafted items and who makes them. Spamming on the fleet isn't the only way to find crafters and, oftentimes, for the specialized items (like specific mods and enhs), it's not enough.
