One change that would help Skarner's new kit
Looking at the pbe feedback boards for the Skarner update, it seems like the main criticism with the new kit is that Skarner is very weak outside of his spire zones and that it is very hard to get the enemy team to fight in these zones. My suggestion is to make Skarners ult a two part ability that allows him to bring his spire buff and zone control with him to fights outside of the jungle.
R - Summon Spire
- Skarner summons a crystal spire at the target location for X seconds. While near the spire, Skarner gains 150 Movement Speed, 35%+5%/lvl Attack Speed, restores 3% of his maximum Mana per second, and gains access to the ability Impale.
R - Impale
- Skarner rears his stinger, rooting his target for 0.25 seconds as he brings it down, dealing them 100% AD physical damage, magic damage and Suppression icon suppressing them for 1.75 seconds. At the end of the duration, the target takes the same damage again. 「 MAGIC DAMAGE: 20 / 60 / 100 (+ 50% AP) 」 For the duration, Skarner can move freely and drag his victim around with him but cannot attack them.
The actual values of the buff and Impale damage might have to be adjusted but I feel like the trade-off of only being able to impale in a spire zone would prevent this change making Skarner too strong and would fit well in his new theme of "you don't want fight me in my area".
