The latest PTR update patch notes are out and hold some interesting info for some of the lesser played characters. It looks like Kennen will be getting a buff, as will Malphite, and Kog’Maw is getting some work that should make him a little more viable.

For Kennen:

Electrical Surge
Ability Power ratio increased to 0.55 from 0.45.

Lightning Rush
Energy cost reduced to 100 from 110.
Can no longer be slowed during Lightning Rush.
Now provides 10/20/30/40/50 Magic Resistance and Armor for 4 seconds.

Slicing Maelstrom
Ability Power ratio increased to 0.4 from 0.33.
Number of bolts increased to 6/10/15 from 6/8/10 (still retains the cap of 3 hits per target).
Removed the cap of applying only 1 Mark of The Storm per target.

Have fun laning against him. I’ve maintained since the beginning that Kennen is one of the strongest laning toons in the game with great teamfighting capabilities. His ultimate was a little underpowered in some situations, but it most cases I thought it got the job done. Now that Surge hits harder, he can’t be slowed in Rush, and his ult hits harder, you will be very hard pressed to outplay him in the laning phase. That ultimate will also devastate team fights. For the mathematically challenged among you, 15 hits at rank three means the entire enemy team is stunned if they stay in for two ticks – yes, two, because of Surge. Granted, that won’t always happen, but it also increases the likelihood that you’ll catch and kill two players, and still have plenty of ticks to chain stun another opponent if he steps in halfway through the ult.

Malphite:

Seismic Shard
Reduced the cooldown to 10 seconds from 12 seconds.
Reduced the duration of the slow to 4 seconds from 5 seconds.
Reduced the mana cost to 70/75/80/85/90 from 80/90/100/110/120.

Brutal Strikes
Changed the active effect to increase Malphite’s armor and damage by 20/25/30/35/40% instead of increasing his damage by 30/40/50/60/70%.
Reduced the cooldown to 16 seconds from 20 seconds.
Fixed a bug where the cleave percent would double dip on bonus attack damage.
Increased the passive cleave percent to 30/38/46/54/62% from 30/35/40/45/50%.
The cleave passive will no longer proc while hitting towers.

Ground Slam
Reduced the mana cost at all ranks to 60 from 60/70/80/90/100.
Updated the tooltip to display how much bonus damage Ground Slam gains from armor.

Unstoppable Force
Malphite should no longer be subject to CC’s while charging with his ultimate.

Granite Shield
The shield now recharges after 8 seconds instead of 10 seconds.
The shield will now automatically restore to full after 8 seconds of not being hit. Previously it would not replenish until a new shield activated.
Fixed a bug where the particle would not appear for a second after the shield activated.
Fixed a bug where the shield strength would not update after buying a health item until a new shield activated.

This is exactly what Malphite needs to make him more fun. Shorter cooldowns, lower mana cost, and a little better synergy between Brutal Strikes and Ground Slam. I also love the cleave removal during tower attacks, as you won’t pick up aggro just from trying to down a turret.

Kog’Maw:

Caustic Spittle
Spell Remade. Now grants:
Passive: Increase Attack Speed by 10/15/20/25/30%.
Active: Deals 60/110/160/210/260 damage and reduces the target’s armor by 5/10/15/20/25 for 4 seconds.’

Bio-Arcane Barrage
Cooldown reduced to 15 from 20.
AP ratio removed.

Void Ooze
Cooldown reduced to 12 from 13.

Living Artillery
Now has a 0.5 AD ratio in addition to the AP ratio.

I’m not sure how I feel about this. It’s obviously tilting him toward AD build, or at least Maldred’s with the passive attack speed buff. I think his real problem, though, was high mana costs, extremely low survivability, and one of the longest attack animations in the game. It forced you to blow skills to last hit creeps, if only because the delay between your attack command and the projectile landing was so damn long.

Riot has been pretty good about leaving vastly overpowered tweaks on the TR until they seem balanced, despite the release of some seriously OP toons recently. I wouldn’t be surprised if we only get one or two of these in the next patch. Personally, I’m hoping for Kennen.
