You're my spirit animal now. I drink massive amounts of strong black tea with milk and I agree, has to be absolutely boiling and I preheat the teapot.

At work I put a teabag in hot water and zap it in the microwave for 20-30s, key to driving out the flavor into the water.

I don't like green tea but I would think that you should experiment with whatever temp gives you the extraction you need. Don't listen to experts is rule #1 when it comes to brewing.
