Both blades did little damage, could pretty much let them hit you. Hammer just gave people knockbacks, no biggie.
The biggest problem with Zelandra will be coordinating hp % so you get max burn time on boss. Luckily we had mostly entire guild in raid finder, so we could use voice comm and 1 shot the boss in the usual 2 burn phases.
No way your normal raid finder pug will be able to do this without taking 15 mins.
