Mordekaiser change
Passive: Idk if his shield is stronger now or not but its 25% of his max hp (131.25 at level 1 (max hp 525) and 491.25 at 18 (hp 1965)) which is weaker than before (around 900 shield at lvl 18) if you don't build hp. But it never goes below 25% now.
Q: Mace of Spades now leaves his next autoattack as normal, then his second does triple that, and his third triple the triple. No more ap.
W: His whirlwind-of-metal ability now causes target ally and himself to run faster towards each other and, if they arrive, deal dmg over time in a circle around each which overlaps in area and damage, then extra detonation damage which heals Morde and his ally for the detonation (heals for third of dmg on minions / not monsters).
E: His cone damage ability is now just as strong in ap and also has an equal ad ratio (0.6)
R: Same, but ghost has less ad, but can now ghost dragon.
So his W has more utility and is quite likely much stronger, his his E is twice as strong, and his Q is probably stronger too, his ult is about as strong since dragon has 100 ad, plus he has about equal damage diversity with his full ad Q, half ad E, and autoattacks, which allows him to switch focus from damage type to damage type to avoid certain defenses. His full tank build is also strengthened.
