What good is a subscription if they remove support?

I assume you're just venting. There isnt really a lot you can do. You'll have the same problem with Xilinx - Vivado only supports the 7 series chips, and ISE doesnt. ISE development will stop soon enough.

I dont really know what you want from this post. Altera supports has been mostly ok for me. Ive had phonecalls directly from very knowledgable people. FAEs are usually just front men who forward problems onto Altera tech support anyway. They often know enough about everything to get by, but not in much depth. When there is a deeper problem they often know who to contact in altera.

What exactly do you want?
