Things might have changed since I played. I quit after the first month but when I hit 50, it took about 4-5 days doing the heroic dailies on Belsalvis and Illum to max out all my gear, You get weapons, every piece of major armor and tokens for all the mods. HM offered no upgrades at that point other than the crafting rare from the final boss. I used those to build the implants, saber and shield generator. Then I switched to Bio and built my rakata medpacks. At the time, the only thing better were some of the raid stuff, but it wasn't worth the time investment for a chance drop of something that added only a point or two to each stat.
