It's not like it is on live where you get embers quick and then unload 3 CBs with massive damage but outside of our your damage is not that great. On beta you do more like a combination of those spells to get food burst like every 45 second. + 3 min cool down.
1cb to get eradication the unload the rest. Spamming cb makes no sense at the moment. PvP wise at least
