I totally agree...I used Cubase for years and I was really surprised that there were no sends for fx channels...
I would use them for instance for drums in parallel compression - to send a bit of the comp channel to the drums room...
or to staple my reverb by using delay fx channels with different times and sending them to my fancy reverb...there are plenty of possibilities...
sure...there´s is a simple workaround....send the fx channel to a group...and voilá ...you have sends again...but sometimes, especially with big projects, it´s better to prevent a big amount of channels...
