With eip-1559 you likely will never see eth mining as profitable again.  Will people tip enough to during congested times to get us back to days where cards are giving us $5, $10 or $20?  Doubtful.

If we lose 20%-40% of revenue and are essentially capped at 2 eth per block it may not feel as bad as a drop from recent record revenue days but over time that's a big loss of revenue.  It may even weaken the coin as gpu's get pointed elsewhere just as new asics come on line making it easier to do a 51% attack.

This is also one of those buy the rumor (which we have seen) and sell the news (which is coming) deals.  I don't think it is going to push the price of eth higher. 

It should be postponed until the coin is fully pos in a few years.
