ADC Kog'Maw buff ideas.

Let me start of by saying I know of the changes on the PBE right now which is removed 20 damage from his E void ooze along with changing the AP ratio to 50% to 70% while buffing his W to 3/4/5/6/7% max HP magic damage on hit from 2/3/4/5/6% max HP magic damage on hit. These changes are a step in the right direction for Marksman Kog'Maw however I doubt they will change much.

Idea #1 AD Scaling - At the moment all of Kog'Maws abilities scale with AP and only one scaling with AD being his ult at 65% bonus AD ratio or 130% based on enemy HP. The most frequent Kog'Maw build at the moment is Trinity Force - Beserker Greaves -Runaans - Blade of the Ruined King - Infinity Edge, and Banshees veil. This plus 9 AD Marks gives him a bonus 138.55 AD. The only impact this has on his skills is an extra 90 damage on his ult (180 based on enemy ad) but that's honestly pitiful. Maybe by allowing his Q or W (preferably Q as W could be extremely overwhelming) it could give him a slight edge with an AD build.

#2 Movement - Kog'Maw is currently placed at 325 movement speed the second lowest base movespeed in the game the only being lower is an unmounted kled at 285. Looking at a list of champions from this only three don't have any reliable speed ups or movement abilities being Kog'Maw, Soraka (while he passive does give movement speed it is situational and not always available to you. Another note is while sorakas do get talisman of ascension I would rather not include items as those again are not always available) , and Anivia. A lack of any hard cc and movespeed is a very bad combination. My ideas are either grant an ability some speed up say his E grants him a speed bonus while on it which would give him a chance to escape some enemies or something a lot more realistic up his base speed to 330 or 335.

#3 Ultimate - At the moment Riot is gutting AP Kog'Maw and has made it apparent they do not like the playstyle as shown by the nerfs. AP Kog'Maws bread and butter was the ultimate and I feel some changes to it could remove AP Kog'Maw completely while making AD Kog'Maw feel more viable. At the moment a standard AD Kog'Maw will have 1252 (1002 base + 250 from sheen) mana. Late game we can assume he will use Q W and E so lets remove 200 mana so hes at 1052. This is enough to fire off 6 ultimate shots (Kog'Maw will have spent 840 mana and have 212 remaining however the nice shot will require 280 mana). Each shot will do 270 damage before resistances which isn't as stong as you might think when factoring in magic resist (a full build Darius would require 31 shots to kill costing 10200 mana.) and health. My idea for this change would be increased damage on each consecutive hit while having a lower AP ratio (maybe 12.5% at 41-100% HP and 25% at 0-40% HP). This would not only be a major buff for Kog'Maw and let his ult be more than a subpar execute/quick sheen proc but be more useful in fights while letting Riot remove AP Kog'Maw. Note I do love AP Kog'Maws playstyle however Riot has made it clear they don't and thus is why the AP ratio nerf is there.

Thoughts and other ideas will be appreciated.

One thing to note is the build used for the damage on ult above is from Champion.gg.
