I agree with bro Ahmad Sharif that some Tasawwuf elders consider joining TJ as demotion.
But we have to ponder why they think so. It is because the faulty attitudes of layman TJ members. If any Murid stays at a high state of spiritual condition and joining with ignorant Tablighi people make harms of him instead of good, then it is a valid attitude.

The situation nowadays has become so bad that some Tablighi so called local elders have a little respect for Ulama/Mashaykh.
For example, in my area some of the teachers of our University are Ahle Shura. Once a professor (a member of Shura) was saying in his bayan- "No Pir is required for your Islah. Just make efforts of dawah, Allah will make your Islah."

Now tell me, if any Shaykh or Alim listen it, will he let his murid to go for Tabligh under this type of elders' supervision?

But it is not only Tablighi's fault. Ulama have become too busy to spend some time to purify the work of Tabligh. The imam of our central masjid is a great Mufti. He was the student of Shaykh Zakariyya .
He always point out the faults created by Tablighi people. It's good. But he has never visited our local Markaz. What's the problem if he sits with our ghair Alim elders and advise them about purifying the effort of Tabligh?
I've seen this attitude among a plenty of Ulama.
