The entire fight has been nerfed, not only the balls. It's embarassing how much Bioware felt they needed to change this fight so the majority of their playerbase could kill it within three attempts.

Easy instance. As stated above, the only boss which provides the slightest bit of trouble is the optional droid boss. The last boss seems as though it's missing mechanics, that or we simply overgeared it. On hard mode we had two columi headpiece tokens drop, one from the optional droid boss and one from the last boss. Also had a tionese grade weapon drop from the second boss with a (52) mod and a (52) enhancement, however the weapon had a (56) yellow crystal with +41 power which is on par with the rakata weapon crystals.
