It’s not about being supportive, it’s about being realistic. Funcom is simply not going to do that 
Honestly, I don’t even know why you proposed the “free Bazaar item” idea. Do you really think that one free item from the Bazaar is an adequate compensation for all those hours you lost? You spent “more than 400 hours” building and crafting and breaking thralls and leveling them, and a cosmetic suit of armor is going to replace all that?
If you’re going to propose solutions, make sure those are related to the problem.
Speaking of which:
A little bit of punctuation would have been nice, but I managed to read through that. However, I’m still not sure what you’re actually asking them to do. Is it like a Siptah leyshrine, where you summon hostile NPCs and then knock them out? Or is it like a golem crafting bench, but for other NPCs? I’m asking, because the bit about the “frost giants” and “black ice” is rather confusing: you can’t knock out frost giants, those are summoned by the horn that Ladagara drops.
