Since you've talked about both FFXIV and LoL, you should know how toxicity can be enabled easily by making statistics available. Heck, even FFXIV doesn't include a DPS meter and forbid using ACT to judge others: should SOLO do the same then, remove the DPS meter and let raid group wipe again and again because of one weight?
From what I can read from your first and second paragraph, you propose to add statistics which would aid in filtering the already low playerbase. Doesn't that go against your "waiting simulator" issue though. This is like group recruitements looking for 85gs/6k DPS and wondering why they take forever to find people... In no way do I see your propositions solving the issue. It would certainly help some people in oneshotting dungeons and going back to sleep for the rest of the week though, contributing to the dwindling the population even more.
"it should not be a customers job to think and implement solutions"
And the solutions do exists, but are they worth it from a company point? To mitigate these issues may require to revamp the game itself (e.g. timegate, gear progression) on a game that already has its content set in stone (unless devs decide to change things for our version, lol). I'm all hear on a solution that would both make the customer and GF/WS happy.
On another noter, "Oh and NA ppl who complain about high ping, need just to move closer." has the same problem (even Riot a multi-billion company can't be bothered to fix it for LoL).
