Since you are curious, I highly encourage you to talk to a priest and present any and all questions/objections you have and see what they have to say. I had very similar objections when encountering Orthodoxy after being a Protestant for 20+ years. Ultimately, every single objection I had, there very good answers given.

It’s worth noting that you may perceive the services (if that’s what you mean by prayer time?) to invoke the name of Mary more than Jesus. That is simply not true. For example, you can search the text of St. John Chrysostom’s Divine Liturgy (which is the main service every Sunday) for “Son”, “Jesus”, and you will find many more references than “Mary”.

In Orthodox services, we also refer to Christ by many names, not just Jesus.  For example, every time we say “Glory to the Father, and to the Son, and to the Holy Spirit, both now and ever and unto the ages of ages” we are giving glory and worship to Him.
