Mercenary Multistrike Supports are damage decreases

Mercenaries' Multistrike and Greater Multistrike causes Strikes to repeat 1 or 2 additional time, while giving 15% more Melee Attack Speed and 15% less Attack Damage.
This means the Support results in 2,25% less Damage (1*0,85*1,15) and simply locks the Mercenary in place for longer.
Please buff it to be more equal to other damage support gems. E.g. Greater Elemental Damage with Attacks III
Supported Attack Skills deal 30% more Elemental Damage

For Example: The Players Multistrike is a total of ~45% More Damage by having 45% More Attack Speed, 20% Less Damage and More Damage on the First and Second Repeat.
