Like all things, some like change and some don't.
If HCL goes away, many raiders will cheer, and many players will leave.
Not sure if the trade off will be worth it.
Just to be clear in advance, removal of HCL will lose a measurable chunk of the player base and after a year, they will not come back.
It is what it is.

Because from what I can see on the audit site, the *total* population of all servers combined increases by maybe 150ish players each HCL, then pretty quickly tapers back down to pre-HCL within a month or two.
So HCL increases total player population by ~10% for roughly 1/3 of the year. Doesn't seem to be a huge deal in the grand scheme of things. Maybe it matters a little more if we assume that the average per-player spend for HCL is higher than Live servers, but still...
Then consider that HCL puts a hit on the LFMs and grouping scenes on the live servers which serves to frustrate non-HCL players, likely causing a small number of them to quit DDO each HCL. This creates a downward total population trend long-term, which is obviously bad for business.
Now consider, how many returning (or potentially even new) players and more importantly how much income will SSG generate by focusing the dev time on the new things for the Live servers mentioned in the Producer's Letter instead of another HCL? Add in some potential retention of Live server players who would have otherwise left during the next HCL.
Taking all this into account, it's easily possible that the long-term net population loss of no HCL probably isn't as large as some people are making it out to be.
Balance that against the income generation and potential new/returning players and current Live server player retention and the whole "no HCL, the sky is falling" thing might not be as big a deal as people think.
