Hey FeralPony, first of all big thanks for taking your time to answer and engage with so many of our questions and ideas! I have a few myself:
First, are there any plans to make runes cheaper/standardise rune cost across the board? My argument for is that in making runes cheaper, players could experiement with some more "Out there" combinations, affecting their early game in such a way that makes certain champions perhaps more usable, etc. I don't think it would hurt anything personally.
Second, is there a sort of wriggles item for AP users coming at all? If you play AP top lane for example, you really need to be sure you don't get squashed by having wards constantly there. Wriggles allows you to have 1 constant ward up, and that's really all you need if you place it properly. This allows you to be in the lane for a long time, which is especially good against heavy pushers (and of course always a good thing). If I'm a tanky AP user top, someone who can actually stand up to a great deal of brusiers, I feel disadvantaged that they can just spam their wriggles ward whereas I need to constantly buy them. I feel if you added this, it would greatly increase laning variety. I know that "tons of sustain is bad", but some item giving like 30 AP, 15% spell vamp, maybe a defensive stat and the ward use I feel would be a good addition. I play Soraka tanky AP top often, and give a lot of brusiers a run for their money, but eventually I need to either go back to get a bunch of wards, possibly letting them push my tower hard if I don't do it perfectly, or risk getting splattered by the jungler/teleport gank as I have no vision. Other APs top with sustain/tankyness would of course suffer a similar problem, whereas ADs can just buy wriggles and stay there until they REALLY need to go back, rather than just because their ward ran out.
TL;DR - Wriggles like item for AP, as they are disadvantaged solo lane vs AD chars (top or bot) due to the free ward spam from Wriggles with no need to recall to get wards/vision.
Thirdly, whilst not my Idea, but I saw mention of an AD spell vamp item; this would be quite well received I imagine as plenty of underused physical damage champs use mainly physical spells rather than autoattacks to deal damage.
Lastly, are there any plans to change Soraka at all soon? Not that I think she is bad or too poweful etc, but AP Soraka is sort of my 'guilty pleasure' if you can call it that >.>, so just curious .
Thanks for reading!
