Agreed. I feel the same when I pray to our Lord. But asking others to pray for us, including His blessed mother is also beneficial.
How would you feel about it if, while you were seated across a table from me, I got on my cellphone and made a round the world satellite call to your cellphone, because I felt you wouldn’t really respond adequately to anything else?
As for purification of prayers that is what the Holy Spirit already does. He hears what we mean even when our words are awkward.
