Comments of chapter undefined of HP: The Guardian

Nice chapter. But MC is really troubling, 1. He is half Phoenix, as bird he should be more comfortable in air then on ground, but still acceptable as can leave as a plot hole for future. 2. But as he is half beast half human with increased strength how could he have a weak grip , when I danger of life and death body performance increases more than two folds. This shows MC sometimes has high strength and some times he is as weak as a normal child which is totally random and looks forced to fit the story line. 3. Also how could he has slower speed then toy brooms even if he is not serious. THIS IS A COMMENT TO ONLY SHOW SHORT COMINGS IN CHARACTER I AM NOT TELLING YOU TO CHANGE ANYTHING IN STORY LINE AND CHARACTER DEVELOPMENT :
