I've been playing Summoner as my DPS alt for a few weeks now (WHM is my main), and haven't really spent any time leveling ARC to get the last two cross-class skills. Looking at what the skills do online, is there even any reason for me to spend time getting Hawk's Eye and Quelling Strikes? Both seem pretty situational, and apply to situations I'm not going to see myself in.

Hawk's Eye - Increases physical accuracy by 20% for 20s. --- If I hit the ACC cap (for myself and pet), this skill is useless, correct?

Quelling Strikes - Reduces enmity generated by each attack for 15s. --- I very rarely draw any sort of aggro, and only ever from DoTs, and this seems to be remedied by the tank (or another DPS/Heals) fairly quickly.

My question is: Should I spend the time getting these skills? They don't seem nearly as necessary as Swiftcast for Healers, and I can't see myself in a situation where I wished I had either. Comments?
