Cocoon cooldown

How do I make Life Cocoon a 55 second cooldown ?
I have Chrysalis PVP talent + 1 Burst of Life.
And my cooldown is 1.7 min.

This might be a bit of a stupid question but do you have warmode turned on? If you don’t, then Chrysalis won’t work.
Also, if you are trying it in non-pvp instances, it won’t work either as you can’t have PvP talents enabled in them.
