For everyone concerned about using Provoke while a Regen is ticking or other members using abilities, it's a non-issue. You typically pull mobs in at least 2-3 per pack. If you are pulling at range and you have a regen ticking on you, pulling with shield lob/tomahawk/umend will be no different than using provoke. You're still going to have to follow up with an aoe threat ability. In those scenarios even using your ranged skill, there will still be two other mobs that would run to the healer. It's not like you pull with provoke and call it a day. You follow up and intercept the mobs on their path to the party with aoe threat.
