-I clearly said what it is the definition of elves this you who didn't bother to read the first post.
No, you specified that true elvhen were those who lived before the Veil cut them off. Then after you were proven wrong you added that the true elvhen that was killed needed to be in his pre-Veil form in order for the kill to count. You changed your demand after it was thoroughly met.
Also don't be silly ancient elves are the only one who reach their true form with the fade energies not other races,this is lore.
But the Hero of Ferelden didn't exist back then, did he? So we can't confirm that he wouldn't have reached the same heights or been able to defeat all evanuris. Lucky for them.
A human can't gain anything from the sun but a kryptonian can there is a similar parallel between elves and other races.
Or is there? Perhaps anyone can learn to tap into the Fade energies given enough exposure to it. Same reason why humans are more influential in the real world than spirits. People understand the Real better than spirits. So the reverse is true, except in the case of mages.
Put an advanced Circle mage in the Crossroads or the Fade physically for a while and see how far they go with it. Especially if there are spirits worshiping them and giving +1s to their stats.
Abelas wasn't in the true elven form and second didn't even fought so you are stretching here,
You wrote, "Elves are the beings that were alive in the pre-veil world with the fade around them(ancient elves+fade)these are true elves". Abelas meets your standards. Abelas got MK'd by the human Morrigan.
it was not even a fight his purpose was to eliminate the well not to fight someone
Ah no. His goal was to stop the unworthy from gaining the Well's knowledge. He failed because he didn't dispose of the unworthy before attempting to destroy the Well. Foolish "true" elves.
so again the moment a human would defeat an elf a true elf(in max power) in a fight i will listen.
No, then you will add more stipulations.

-Solas crushed a commando of Qunari with a thought,has thousands of years of knowledge,one of his artifact possessed immense power and dealt with god kings and also manipulated relaity with the veil.
Wynne can petrify people too. Solas as thousands of years of knowledge and nothing to show for it. The orb had power he couldn't unlock himself. Kind of defeats your argument. Dealt with "gods" by doing something with the Veil. What that was is not yet known.
The HoF is nothing more but mere appetizer for a god
Defeated Gaxkang the Unbound, when the evanuris could only banish him.
