Abhi Thank you for this helpful, stickied page. I never knew there were different types of tiers before this post of yours.
As of today, it is not updated, so I want to mention that if you want to keep it updated.
I do have a suggestion about that. It seems to me that it requires your effort to update the page every week. To me, you have better things to do!
Presuming it is not easy to automate it, it seems to me that a static page would be 90% as helpful. Choosing the correct tier does not, for me, depend on the specific week's offers, after all the offers are almost identical every week. (Or am I wrong?!?) Or to put it another way, the relative costs and quality of the equipment on offer stays the same week to week.
tier 1 is never a good use.
tier 5 is for people with more money than I can imagine to spend on a video game
tiers 2-4 offer a balance between gems and quality of equipment.
So I am thinking an illustration, one for each region, of the typical values would be sufficient.
