Rune Conversion Rate

The flat conversion rate for a variable rune cost is extremely poor. At minimum should be a tiered or ratio conversion, not by rune count

820 IP runes for 100 BE (12.2% exchange) and 2050 IP quints for 300 BE (14.6% exchange)??

Just taking three 2050 quints would be 6150 IP which is almost new 6300 champ, yet on exchange I get 900 BE towards a 6300 BE champ which is less than even 15% towards a new champ.

But hey, some naysayer will tell me that I got good use of my 3 move speed quints I bought last October and well worth the opportunity cost right? [darius-angry]

And what about Tier 1 & 2 runes that I actually paid full price for 5 years ago? Cant tell me I've gotten good use from those all this time because they were just fillers for the poor until they could be replaced
