I assert that you have never played a summoner or with one, or have any idea what you are talking about.

1. Please, I never, ever said they use your attributes. Using the EXAMINE option on an incarnate shows THEIR attributes which scale with levels and also can be buffed with encourage etc. THOSE attributes are a VERY big multiplier.

2. The crux of the argument is "Incarnates overshadow self-cast builds because 10% is too much". Proof is that incarnates have access to almost EVERY multiplier that self cast builds have (they have their own pyro attribute, int attribute etc) and on TOP of that have an OBSCENELY high multiplier.

If you think any of the above doesnt correspond to reality all you have to do is get an incarnate, buff it, right-click, press "EXAMINE", and hover over the "DAMAGE" field. Then all the multipliers that take a normal amount of base damage to an obscene quantity become obvious. (hint: try comparing that to the ONLY two multipliers a caster gets, +increased from int and +increased from pyro.)
