I hope riot revamps the whole rune mechanism next season
Currently, runes are a factor and they are needed in every game. I think riot should do a revamp to the rune page.
First off, they should start re-arranging and re-doing all the rune sorting in the client. The view of the actual rune page is pretty much a bit "worse" than the old season 1 or beta rune page. A visual and unique sound effects would be a great addition to it, making to appealing to add/remove and mess with it.
Second, have a way to re-do the runes when adding. Currently we have 9x glyphs, marks and seals and 3x quitessences. Maybe so something creative with it? (I have no ideas for this now :( )
Third, now that we have different masteries, a few runes should be reworked to be better (like the ones who nobody uses) or worse (depends, but don't count on it).
Fourth, add new runes to it. My instant idea is tenacity or scaling tenacity. Might not be a great idea to use it, but it's still "new" and a few champions could use it.
Another idea is bonus AD/AP/armor/magic resist from items. Let's say 5% extra armor from runes and you still have 5% more bonus armor, which equals to 10% bonus armor from items. Same with other stats like AD, AP or MR.
Another idea are Aura based runes. This might be tricky, but it should be very helpful in teamfights. Remember pre-rework Sona? She had sweet, sweet auras that helped alot. Aura based runes should be half efficiency for other runes (instead of 1 armor seal it's 0.5 aura armor seal). Scaling is the same. Instead of 0.17 armor per level it's 0.085 aura armor per level). Sacrificing half the efficiency of runes for your team can help a bunch and it helps a huge load of diversity, not only in solo queue or dynamic queue but in competitive.
What do you think?
