Not that anyone needs one more opinion here, but its the weekend so, well, screw it.
It would be simple for a Diamond license to also include access to the same slimmed-down products further down the tree, so thats not really a valid argument per se. It would be a simple demonstration of goodwill to do this, but EW are absolutely not the company to run to for simple demonstrations of goodwill.
It comes to this. Never buy EW at full price. Ever. Always wait for a sale, and then wait some more for a better sale.
Support isn't great. They won't add any more goodies to an existing product. They may fix issues, they may very well not. All of which makes waiting doubly good sense. After a couple of years you'll know exactly what you are getting, anything that might get fixed will have been fixed. You'll know that you can't modify the CCs, so find a way for your DAW to do so. If it can't, you're outta luck. You'll be able to find out all the other strengths and weaknesses too. You'll get it for a steal, among the very best buys in the business, but your purchase will be the beginning and the end of your relationship with EW regarding it.
Treat a new EW release as a pre-release.
The market may be brutal, but it is always right. According to the Libertarians. East West are the Libertarian dream.
