"Many of us" can mean me and many others. It doesn't mean the same as "everyone." I made no statement indicating your opinion was invalid. You are the one trying to say I'm the only person with an issue and trying to invalidate my complaint.
Conversely, you're trying to say that your personal tastes are widespread and thus, carry more weight. Both are wrong. It's much better to simply speak for one's self and avoid the whole issue.
You find big holes in 5e. But, you then point to some very, very niche products - mass combat rules? These were never a big part of the D&D experience in any edition. Psionics? Seems to be popular, but, again, they were always something that came a fair bit later down the road in any edition other that 1e. And, you complain about the lack of module support, but, again, there are some thousand modules for 5e on DM's Guild. Of various lengths and level support.
I mean, there are 344 3rd tier 5e modules (levels 11-16). I'm pretty sure you can find a dozen adventures to run at those levels if you wanted.
