I was under the impression that all companions across the board were to be equal class vs class skill

I Have Lana Beniko with 34 inf and she does a soothe heal for 11993

Veerona Denz with 41 inf and does same soothe for 10925

Now I just got Veerona, and just hit 100 kills with her doing some quests today, does that have any effectiveness in anyway at all?

Your influence rank with them determines power, individual numbers don't seem to matter such as 400 vs 500

but rank 1 will do worse than rank 10

Right but an Influence 34 should not be more then an influence 41

Both Lana and Veerona have the same base stats when you look at there stats in the companion window

What changes is my Presence Buff, with Lana is 2878, with Veerona 3228

So the influence is registering, but at any event Veerona's skills are lower no matter what stance she is in, dps, heals or tank, should still be higher at 7 levels more

Veerona does have more HP though, but ability skills are lower
