NA Buffs Question

[drgantz]

Do buffs for Wild Growth, Wild Bastion and Overgrowth work as an area or a group of people?

For example, I'm playing an NA Def and my group is about to attack a group of baddies.  Should I cast a buff right before we attack so that the buff will affect everyone before we go in, or should I wait for our attack and then walk near my group of allies and cast it so that they will all be within my radius for the duration (unless they move out)?

I generally hit the buffs before combat starts.  The only power that's a patch is life giving spores, everything else stays with the allies as they move.

I do at first when it’s an option. Most of the time people just run around like crazy. I just hang out in melee for aoe hold power and use the three buffs then on the tank or try to get as many as possible.
