He need new mechanics his kit It's boring actually and his E feels very useless with and very easy dodgeable skillshot and non damage
Now my thougths:
W:
SHIELD: 80 / 135 / 190 / 245 / 300 (+ 80% AP) to 60/70/80/90/100 (+ 8/9/10/11/12% of Skarner's TOTAL Health)** and 15% of tenacity during the shield.**
Base shield value lowered to 60/70/80/90/100 from 80/135/190/245/300
Shield now scales on 8/9/10/11/12% of Skarner's TOTAL Health from 80% of his AP.
Skarner now is more oriented to the tank side (after the 2nd rework), and are a very few items that he builds with ap (ICB, Trinity and maybe Abyssal Scepter). So that 80% AP is very useless. I mean he need some reward to build tanky like Sejuani or Nautilus and that "TOTAL Health" is the thing that Skarner need in his kit. A huge shield that make him feel like a fast-truck. You are the responsable on the Skarner rework so please change his "magic" Shield into a very powerful "solid" shield. IMO has more sense the TOTAL Health scaling instead the AP...
E. Bracken Crystal Wall
RANGE: 1100 COST: 70 MANA COOLDOWN: 2 RECHARGE TIME: 39/ 35 / 31 / 27 /24
PASSIVE: Skarner generates a new crystal wall periodically, and can only store up to 2 crystal wall at once.
ACTIVE: Skarner creates an impassable wall of crystal at the targeted location for 4 seconds, perpendicular to which way he's facing. After the 4 seconds the wall explode causes magic damage and root all nearby enemies within 200-radius of the wall.
Skarner can use Impale on the crystal walls and drag the walls to an another direction Skarner can reactive his Impale to launch the wall to a target location. When it lands, it deals magic damage to all enemies in the area of impact and Stun them. (Range 1100)
WALL LENGTH: 400
ROOT DURATION: 0.5 / 0.75 / 1 / 1.25 / 1.5
MAGIC DAMAGE: 80 / 120 / 160 / 200 / 240 (+ 45% AP)
Crystal Wall on Impale:
Stun DURATION: 1 / 1.25 / 1.5
MAGIC DAMAGE: 150 / 225 / 300 (+ 70% AP)
Apart of his Ult his kit it's very boring, specially his E, an linear skillshot with non damage is not the best example of "fun", he need more crytsal in his kit, also a better mechanics in his kit. The damage of his E does not exist. I'll prefer make a completly new E like the previously showed, It's very fustrating see that ridiculous damage, is like "nothing"..
