It got durability upgrade, without it small arms can take it down and it has significantly less health then 222 out of the gate.
In addition, it can engage infantry exclusively, contrary to infantry, lvs and planes 222 can engage(ok, maybe M20 can shoot at planes too, but 222 can actually take them down with relative ease).
Unupgraded M20 has less EHP vs 1 pen small arms then 222, upgrade cost is worth more then 10 fuel.
Its not "fuck ton less health", but its 240 EHP vs 1 pen weapons in favor of 222.
222 also has massive advantage in durability against any kind of AT weapons due to having that extra health.
Skirted M20 got more EHP, but resources combined, it also costs more at the end and its firepower stays meh at best.
Word of advice:
If you are going to use quotation marks you have to actually put the exact words and not change them. Else you are putting words to other people mouth and that tantamount to lying.
Especially if it being done to prove me wrong.
This is what darkarmadillo wrote and what I responded to:
Depends on if you bundle in the side tech you need to unlock it.
But at any rate, it's a fuck tone less durable than the 222 and comes a smidge later. Idk what you want from me here. If you want smoke on it there are a number of doctrines that provide that.
Yet you write:
Its not "fuck ton less health",
In addition that claim that:
222 also has massive advantage in durability against any kind of AT weapons due to having that extra health.
Is simply false. Many AT weapon do 160 and need 2 shots to take vehicles with both 240 or 320 HP.
The stat of EHP for these vehicles vs penetration 1 weapons.
M20 no skirts EHP front 2.640 Rear 1.320
222 EHP front 3.060 Rear 1.440
M20 skirts EHP 5.280 Rear 2.640
In other words 222 has around x116% more EHP than the non skirted M20 while the skirted M20 has x173% more EHP.
My point still stands the 222 is only slightly more durable than non skirted m20, while the skirted M20 in fact more durable.
