Content Type Hub - It's hard to say I love you

Recently some other developers suggested using content type hub for a client project and it created massive overhead:

• Added complexity for deployment
• Lots of errors from content type publishing
• Lookup fields are not supported and we have to use metadata fields, again.. more overhead.

My suggestions for anyone what to try content type hub:

• Do NOT use it if there's no requirement to consume content types by multiple web applications
• Do NOT use it even you need simular content types in different web applications but you need different customization
