Skarner's Crystal Spires
Let me start this by saying that I love Skarner. He is my favorite jungler and honestly, probably my favorite champion. I have loved the guy since I first started playing League and saw my friends using him. I've adapted his "I cannot be impeded." and "Organic weaponry is inconsequential." ("Why not just head over to this 'consequential' place and get it?") lines from Battlecast Alpha Skarner as a catchphrase of my own, often using them for comic relief with my friends. Skarner was the first champion I was ever excited to try and genuinely interested in playing. This scuttle-bug of gems was and continues to be one magnificent hype train for my friends and me. I have fun when I play Skarner and I just generally feel better when playing him.
Having said this, I must comment on the proposed changes to Skarner's kit. More specifically, his new passive "Crystal Spires." In short, it seems like a horrendous, terrible idea. I understand the desire to add new mechanics to the game, however, this is a poor attempt at creating diversity in the league.
Initially, it seems alright, Skarner gains power while in the area, meaning you'll prefer to fight there, not unlike Trundle with his Frozen Domain ability. However, after giving the idea moments of thought, glaring flaws appear. Unlike Trundle, Skarner cannot move his domains and as such is reliant on fighting within certain areas. This means Skarner will depend on fights taking places in awkward, clustered spaces that no competent player would want to be caught out in. While it does increase his ability to clear some of his jungle camps, the static position of the domains limits his power to incredibly specific portions of the map. His power is no longer dependent on how well he is doing in the game, how well he farmed, how well he aided the lanes, or how well the player can play Skarner but rather where the enemies choose to fight him! Imagine if Nami could only use abilities while in the river, imagine if Brand couldn't use abilities in the river; fights that included them would be dependent on both team's positioning rather than anything else that the single player can help determine. This having been established it can be determined that this part of the passive will be useless/unusable for the majority of the game, meaning Skarner will effectively, like a Karthus or Zyra who never die, have no passive ability.
Unfortunately, it gets worse for the Crystalline Chelicerata. His passive that he receives little to no benefits from can easily be turned against him to produce a lead for the enemy team. The obvious being the dedication of gold to his enemies. While some people claim this is "not going to decide anything significant" it may prove to be the kiss of death for Skarner. While 15 gold may not seem like much, it also gives the enemy motivation to not only capture the points but to contest them and to invade Skarner's jungle in order take them. While the spires placed near the enemy buffs are obviously there to encourage counterjungling, Skarner still proves to be a relatively weak counterjungler. That being said, it will be easy for the enemy team to recapture the points, granting them more gold. Everytime Skarner enters the enemy's jungle to take back the spire, he is putting himself in danger for very little reward. Even if he takes the buff or another camp, he is granting the enemy more gold in the long run and stands very little chance of being able to defend his position, becoming reliant on assistance of laners to prevent death. The Crystal Spires may also increase the counterjungling Skarner suffers from. While the enemy will run the usual risks that come with counterjungling, they can use the spires to their advantage, baiting out Skarner or his teammates out of position and into the jungle where they can be easily ganked by wandering laners or by the more powerful of the counterjungling champions. Those champions that are more apt at counterjungling will be able to abuse the spires to generate even more bonus gold atop the gold they are leeching from Skarner's jungle. It is because of this that in most situations Skarner players may find it best to simply ignore other the spires and simply use the ones in their jungle, removing a considerable chunk of usability from his already weak passive.
Also, how does this fit his character at all? Crystal spires? He's fights for Shurima now and guards an ancient power while underground as featured in the most lazily slapped together three sentence lore to ever be added to League of Legends. Capturing points? Playing king of the hill? His passive should about being unlocking ancient secrets lost to the desert, embracing forbidden powers buried deep beneath the sand, not a watered down version of a bad 5CP map from TF2!
TL;DR - Riot hates Skarner and all Skarner players but can't admit it so they give him a terrible passive to get him killed more and to assist the enemy team.
TL;DR - Riot thought people liked to play Dominion.
TL;DR - There is little to no motivation or benefit from capturing the Crystal Spires as Skarner. At this point, they serve mainly to assist the enemy team and to open Skarner up to more counterjungling. It also makes no sense in relation to his lore and the changes as a whole force him to play out of the jungle (not complaining just pointing it out).
Please don't ruin Skarner, he is my favorite.
