Kakashi Lightning Clone Rare Mob Mod works strangely with Merc

When using a merc, I proc the kakashi lightning clone rare mod for both the merc and myself AND it always procs 2 of them, near me and only me. I never did AG in any serious way so I never had this problem before.

I'm not sure if it's a bug or not but it would be really nice if that just got fixed. When I do SRS, I don't have 20 lightning clones. AG is a minion and I understand merc was well worded as a variation or exactly similar to AG.

If thats the case I would think there would be one of three outcomes:

1) Only one lightning clone
2) one lightning clone for me and one for the merc
3) Two lightning clones based on who has aggro where the merc can take the aggro

That's the other thing, even when the rare is taunted...the lightning clones only go after me. My invincible merc was intended to sort of take some damage. I've been close to soft locked multiple times trying to kite the rare somewhere and then get as far as away as possible, as quickly as possible. In some instances I've been able to kill it. But I'm still just leveling through the end of yellows right now. I really don't think this is working as intended OR it was never investigated.

Edited to be more specific.

Bumping b/c I didn't realize I didn't specify that it procs two of them instead of one and both of them proc near me making it extremely hard to either tank or get away to cast more spells.
