With the release of mayhem 4 Malawian takedown and the new anointment deal 50% extra elemental damage for 10 seconds after action skill end we have entered into an anointment meta. The use of grenades and shields with this anointment is heavily advised in order to clear this content.
Why this is a problem. The action skill end proc is not equally accessible to all characters and play styles.
An example with flak. Rakk attack does the most damage out of all his play styles simply for anointment uptime. The fade away build has moved away from GITM and towards brainstormer megavore head count and keeping anointment buffs active all the time. Even the gamma burst build the move is to constant swap to a gun that has give an extra charge of rakk attack in order to proc the shield and grenade anointment.
The solution make a new anointment while an action skill is active. This will allow all characters and play styles to access the extra damage required for mayhem 4 content.
