Luminescent Staff questions

45 Druid here saving for one of these but I am having second thoughts.

Can you really get a cast off without getting hit due to the 10 second cast time on ensnared mobs? Is the recast time the same 10 second cast time? It llooks like they got for about 5k plat and I am still saving but I have yet to see one come up in EC chat. Are they hard to come by? I would have had the 5k by now but I spent a lot on gear upgrades this week and finally got over 170 now my wisdom is 199 but will drop 6 when I go 2h blunt. Only thing bad is my 2h blunt is only 53 but both 1h skills are maxed
