I actually thought I was pretty solid sitting at 40% with my HC's, using them pretty much for everything. Tbh, I don't think that's really bad at all, and pretty sure that people with extremely high percentages are inflated due to replaying mission checkpoints like the first moon mission or Siege of the Warmind where they just shoot a line of thrall in the head running at them over and over to complete bounties. From every other game I've played and seen player stats, if you're anywhere 40-50% precision you're good. Your numbers are always going to take negative hits if you continue to play with that weapon type in situations where they may not be suited.
