Good day, i m not found something about it. Then i have suggestion.
Now skill otherworldly whisper (elite-skill warlock/druid) cast on 6 players. Suggestion: make this skill on raid (raid-buff and raid-heal), after increase atk and m. atk from 3% to 3,5% (or 4%), total we have 17,5% (or 20%) on 5 stack buff atk. and m. atk. It should be special for warlock/druid.
I think the players will choose between warlock/mage and warlock/druid in party or both.
Have a nice day.
