just hard reduce the cost of level 30 runes/pages
i've done my FWOTD and then some every single day for 3 years and i still don't have all the runes/pages I would like too.
(which is largely due to buying 6300 champions instead) and I still only have around 50~60 champions.
I have 10 rune pages, 2 of which were free (bought during buy one get one free eras) and I still dont think its enough. 4 are attributed to AP mid lane, 2 for jungle (tank vs fighter) 1 for ADC, 2 which are galio specific. and the last one is for zed. meaning i dont even have a support rune page.
runes and the necessary pages are too necessary to compete on a ranked level, just to not horribly feed/lose lane its not necessary to play expensive vs inexpensive champions.
I recommend a 20% or more hard reduction in price just to make it easier for players starting out to head into ranked. expanding their champion pool is already enough of a task.
