Parche 4.7
Miss Fortune
More like Mage Fortune amirite?
We saw a unique opportunity to support Miss Fortune's off-builds without impacting her game health and play patterns. This is a fancy way of saying we added AP ratios to Double Up.
Q - Double Up
NEWAP RATIO ON 1ST TARGET HIT 0.35
NEWAP RATIO ON 2ND TARGET HIT 0.50
Kog'Maw
R - Living Artillery
NEWUTILITY Mana cost is now displayed on the cast icon (similar to Kassadin's Rift Walk)
BUGFIX Tooltip corrected to display the actual range (1400/1700/2000 ⇒ 1200/1500/1800)
Twitch
We're ironing out some minor issues in the wake of Twitch's VU. We're also reviewing Rat-a-tat-tat's interaction with structures as we work on its inability to target Inhibitors or the Nexus.
General
RECOMMENDED ITEMS Now includes a trinket
AUDIO Fixed a few bugs preventing several VO interactions from working
Q - Ambush
BUGFIX Fixed a display bug where Ambush's cooldown would appear to start when Twitch entered stealth but reset to its actual cooldown once the stealth effect ended.
R - Rat-Ta-Tat-Tat
BUGFIX Fixed a bug where Rat-Ta-Tat-Tat could sometimes critically strike towers
Heal
When we added more utility to Heal, our focus was to create a spell that added depth to the summoner spell pool while also giving heal-focused supports an ability that let them remain effective against Ignite. On live, however, this wasn't the case as it was primarily being picked up by solo laners to circumvent burst-heavy aggressive play (particularly for champions whose abilities were affected by Grievous Wounds).
REMOVED GRIEVOUS WOUND CLEANSE Removes Grievous Wounds
Trinkets
STARTING COOLDOWN 120 seconds ⇒ 30 seconds
Dragon
GLOBAL GOLD REWARD 125 gold ⇒ 145 gold
Turrets
NEW FORTIFICATION All outer turrets now have Fortification (added to Bottom lane)
FORTIFICATION DAMAGE REDUCTION -20 ⇒ -30
FORTIFICATION DURATION 480 seconds ⇒ 420 seconds

El cambio al Heal es una pasada, quizás vuelve el barrier.
