What skills to add on Guderian (Controversial!)

Im a staunch rumor + explosives, the orthodox. What do the rest think?

Oh yeah, would you give your reasoning too?

According to my analysis:

Rumor IS very useful (especially in the end games) and it gives Guderian a solid defense.

Machinist is also wonderfully great! It can heal Guderian 600hp during your 40 turns conquests. It is multiple times better than cover (do the math).

Plain fighting is not so good because in plains you don't get any coverages from panzer and artillery attacks and you won't be able to fight effectively in other terrains or defend a city.

Cover is much inferior to machinist as it only covers 10.8% damage from the enemy (12%×90%=10.8%). Imagine doing a mission of 20 rounds where you get an average damage of 50hp/turn. That means you get a total damage of 1000hp on Guderian. Your cover only blocks 108hp in total (1000×10.8%=108), while machinist heals 300hp (15×20). Machinist is almost 3 times more useful even when you get such a high average damage.

Tide of iron? Unreliable..

Ace forces? Not that useful, especially on Guderian which you would only assign to high ranked panzers.

Crossfire? Not very useful when you already have Rommel and only have 1 medal for crossfire. It's also inferior to armored assault and doesn't trigger when attacked by artilleries.

Welcome, carpet bombing guy😄
Well, here's my viewpoint. Guderian is a pure combat general, thus we must treat him as one. Giving your generals explosives isn't a bad idea either, but not [specifically] on Guderian, as cities are not a big problem (you can destroy them easily without explosives. But guess what? He is a very important man and he must deal with the terrorist gangsters before they crush your units. Therefore he needs a high survivability to maintain his fitness (because strength will decrease when your units' hp drop below 50%. He is like the grandfather of all your troops. He protects. He attacks. He leads your offensives. And most importantly, he must survive. 

Also, if his survivability is high, he can be alive until the end of your campaigns/conquests, which means he can do more damage. Survivability = damage output. As for the citiy-crackings, you don't need Guderian, your other troops can take them of easily, the main problems are the terrorist gangsters. After you take out their generals and first wave attack, the rest will be much easier (airforce/missile+paradrop=victory). Also, there are challenges that will force and exploit your generals to their maximum limits (such as conquest 1950 Greece, Thailand, RoC, Denmark, Norway, Sweden, Cuba, Turkey, etc; conquest 1980 Cuba, Thailand, Spain, Iraq, Turkey, Egypt, Germany, etc). So better be ready for those.

Btw, if you need an explosive general, you can give it to Yamashita/MacArthur and put him on a stacked mechanized infantry.

 I go with rumor and explosives as my choice, I have played WC4 so many times now and at one point cloud saved right before I added a new abilitys and tried it out, then I restarted and tried another out, Imo i think explosives and rumor are good.

I use gunderian to open up cities and take care of forts when needed. he is my second tank gen most of the time, (my main account I have manstein, zhukov, gunderian, konev, rommel, nimitz at the moment). its the most i have found success on in campagin missions.
