The hard mode tag denotes that it's an 8 player primal instance more than anything. I can see your trepidation, I experienced Titan's fury back in the Darklight days, but with the inflated ilvls and echo buffs, these fights don't prove much of an obstacle anymore. It's to encourage players who are in a situation much like yourself to easily clear this content and not be roadblocked going into an expansion you've paid for. The quality of the story also improves further down the line, and should be another incentive to keep pushing you along. Welcome back, and good luck in your travels.
