Game Mechanics Aspect of Beckoned Legion

Lately I have been enjoying this new update with my Summoner Shaman.
As summoner there is one Fabled aspect for buffing summoner.
But when I first saw it I thought it was a nerf if you have a high number of puppets.
Then I made some calculations.

Base puppet master have 20% of DPS per Puppet summon
Base DPS from puppets without this aspect:
with shepherd 14 sum = 20*14 = 280% DPS
without shepherd 6 sum = 20*6 = 120% DPS
level I
with shepherd 15 sum = +5% DPS / 19 * 15 = 285% DPS
without shepherd 7 sum = +13% DPS / 19 * 7 = 133% DPS
level II
with shepherd 16 = +8% DPS / 18 * 16 = 288% DPS
without shepherd 8 sum = +24% DPS / 18 * 8 = 144% DPS
level III
with shepherd 17 = +9% DPS / 17 * 17 = 289% DPS
without shepherd 9 sum = +33 DPS / 17 * 9 = 153% DPS

Conclusion: This aspect is weaker the more minions we have. That should be changed
Here is why:
First argument: The usage of this aspect is not for full summoner build but rather for a player who takes summoner as a secondary tree and I think the aspect of a summoner archetype should benefit summoner as a primary than as secondary tree.
Second argument: More summons a player can have means that it takes more time to summon them which increases the time to reach full dps potential.
Third argument: If we add a new mythic aspect for summoner to the equations then the numbers are in negatives.

My suggestion is: Remove the dmg reduction or change the aspect entirely to do something different.
Idea #1: It will increase walk speed of all summons. Because in game there are a lot of dashing enemies or enemies that are just too fast for them, so this would help with that.
Idea #2: If we want to preserve the idea of increasing DPS, instead of increasing the number of minions, we can add Attack Speed to puppets.

 

I believe it isn't actually a damage reduction for some funny reasons. I remember Xavier talking about it with a player.
