Here's our progress so far:
While doing Demon Hunter skills, I noticed a few oddities, very similar to the issue here: http://diablo.incgamers.com/forums/s...ion-for-skills
Note that these are all very minor issues.
1) Companion has "This skill is affected by your characters: Attacks per second (set to 1 for example above)" both in the skill's tooltip and in one of the rune tooltips. It's fine in the skill's tooltip but creates confusion if it's also in one of the rune's tooltip.
2) Cluster Arrow has "This skills is affected by your characters: Ballistics" in Maelstrom rune tooltip. Ballistics increases the damage of your rockets so it should be in Shooting Stars tooltip since that's the rune with rockets. I might be wrong here but I don't think Maelstrom is affected by this passive.
