One issue about the building approach seems to have caused a division in the body. We are seeing the use of titles among overseers. I find this mostly among our Black brethren. Reverend is now being used in white assemblies. I know of one overseer who has listed his name as an apostle on side of the church van. Preaching robes/garments are to show a higher priesthood over the body etc. One minister I seen looked like the pope and carried a staff. These issues would not manifest in home assembly.
For me I could worship anywhere. Home assembly has its issues too.
