The real reason veteran players are unhappy with the rune rework:
Honestly the reason veterans aren't happy with the proposed update to the runes system isn't because the replacement isn't exciting or good. It is very exciting and a much needed step up from the current archaic system.
The reason we are unhappy is because we feel as though we effectively HAD to buy runes to even play the game up until now, so the notion that "we are replacing the current rune system with a new one, but we aren't refunding the ip that you basically had to spend as a matter of course" is offensive to us. We are especially offended by explanations that don't seem to account for our personal perspective on this matter because it feels like an insult to our intelligence.
There wouldn't be an issue if IP were just something we got "for free" for just playing the game-- but from our perspective it wasn't. Runes were priced in such a way that many of us felt that we couldn't afford to buy champions early on with IP, because runes could ONLY be bought with IP and were very costly. So with IP being a limited resource and not enough of it to buy both champions and runes, we chose to purchase both by spending money on champions.
The choice given to us was basically "spend ip on runes or you can't really play" and "if you don't have ip, spend money on champions or the lack of opportunity in champion select will occasionally cause you to lose." This was especially exacerbated by RIOT's early history of balancing league in a whack a mole fashion in season 2 and earlier that generally made it so that newly released champions were almost always overpowered because they weren't "wacked" by Nerf Master Suck Town yet.
Eventually we expanded our roster to a minimally viable size and grinded a few basic generalist rune pages-- then we were able to effectively play the game and grind up enough IP to buy most or all of the runes and champions. But that initial grind still sticks in our minds, and we totally agree that this pointless grind isn't something that makes league a better game.
If we had the choice, we would have spent IP on champions rather than runes-- we didn't have a choice though, not really. We understand your position and we even agree with the direction in which you are taking the game, we just feel like you don't see it from our perspective. We feel that you gave us a false choice and then told us our choice was wrong. Its kind of like having a bad Dungeon Master tell you there is a room with two chests and one of them is booby trapped, but it turns out that while one of them technically was booby trapped, in fact both of them were.
We couldn't NOT spend IP on runes to play, and yet it appears that spending IP on runes was a mistake. Some of us only bought a small subset of the runes, only the ones we really needed. Most of the long time veterans bought every single rune because we couldn't imagine that it would be a mistake to do so, and we had nothing else to spend our IP on after collecting every champion.
Now all of a sudden our vast reserves of IP can be spent on things besides the occasional new champion-- its now called BE and it can be used to forge skins and other content, so we are happy. And yet, the runes we actually bought-- specifically the IP that backs them, have burnt up and are now worthless, so we feel unhappy. The most aged veterans don't really care because they are sitting on hundreds of thousands of IP and the 150 thousand they spent on runes is marginal. There are other veterans who have collected every champion and every rune, but haven't yet amassed a horde of IP, and they legitimately do feel cheated because you all of a sudden made an enormous chunk of their possessions worthless.
Replacing the rune system with a better one is good for everyone, but replacing the work that people put into amassing their current collection of runes with value equal to 12% of that work is not good for those people. From your perspective you are just giving everyone all the runes and are additionally giving away some free BE to people so you feel magnanimous and can't imagine why people would be frustrated. From our perspective you are telling us that the time and effort we spent to gain a competitive edge by increasing our opportunity in champ select by amassing a collection of runes and rune pages was worthless because you've come to your senses and decided that the playing field should be even-- but you made this decision only after we made the choice to spend that IP
From the veteran's perspective you punished us until we bought the runes by giving everyone who did buy them an opportunity advantage and then you punished us for buying them by deleting the IP we were forced to spend on them instead of champions-- almost certainly because you don't want that IP to be spent on champions or skins when real money could be spent instead.
We know you are trying to stay in business and we weren't asking for a mountain of free stuff, but you didn't even offer us the ability to recoup our opportunity value by giving each player a discount on things like skins and champions in proportion to the opportunity value lost by that player in the old rune system based on the number of runes purchased. Supposedly the BE we receive is supposed to function sort of like the aforementioned discount, but it isn't the same thing because the value of even expensive exotic runes in this regard have become the same as the mundane ones, and they are all less valuable. What we would have preferred is something like a 50% discount on future purchases until we exhaust the value of what we spent on the runes, because at least that way we could eventually realize all the value we had accumulated in those runes.
You aren't really seeing it from our point of view, and that aggravates the hell out of us. You basically don't want us to have 100% of that value back, you want us to have 12% of that value back. On top of that you are making enormous IP sinks like the limited edition WW skin, and everyone can see you are just trying to burn up as much BE as possible to destroy as much currency as possible so that you can make everything you are selling artificially more valuable. Its scummy.
