Playing primarily soviets, I don't believe they need a buff.
Don't use them for damage, use them to push troops out of cover so that your conscripts can tear them up in the open. The burn is damaging enough to deal with support teams if they don't start moving immediately.
Alternatively, you can throw them ahead of advancing infantry to make them slow down or burn a bit moving through the splash area.

I rarely kill a squad with a molotov and i am ok with that as my prime motivation is to deny a zone to the ennemy. If people keep wanting to compare renades and molotov lets observe that exemple : two of your cons squad got caught by an entrenched HMG, one is far one is close to the gun, you have a window of 3 seconds before watching the red triangle pop.... you throw a grenade with the closest cons squad.
2 solutions :
-You throw a normal grenade and the hmg take huge damages, maybe loose a squad member or two...and keeps firing at your shootaboyz, pinning them and forcing a retreat.
-You throw a molotov and wait patiently one of the two answer of the ennemy :
-he dies in the flames, back on your feets boyz take this fuel point!
-he retreats from his cover/building, back on your feets boyz, da fight iz not over waaaagh!
With the molotov you lost 1-3 soldiers but won the engagement.
Molotovs are a frightening weapon. It is cheap because it is often paired wit
WAAAGH HURRAAAY.
That beeing said, the OKW molotov seems one step above...
