Time to sigh more.
If Guards was actually effective itself versus tanks like an AT gun, AND had 60 range, then yes, button could be more OP than TWP.
But still, im wondering what the average Ostheer player did back then, build only 251's and Ostruppen instead of the units that were good and crushed the Soviets? Guards werent obersoldaten, contrary to fake misconception.
No, but a good player could shut down a Ostheer player who didn't go elefant's rather quickly because the roaming band of guards could deal with enemy infantry AND make it so your tanks could surround and kill his tanks.
Old Button meant with a minimal amount of micro, as in moving your AT guns and TD's into range, you could button an opponents tank and kill it fairly fast unless it had a largish health pool like a Tiger.
The Ostheer AT gun can't sight for itself, and the stun takes a minimum of 4 seconds before firing because the AT gun needs to reload before firing the stun shot. The Ostheer AT gun is also fragile and can literally not do anything to enemy infantry, while guards with old button could. And the fact that you kept the enemy armor support fleeing meant your own tanks could roam the field with supremacy.
It is an L2P issue as your player card shows that you haven't even played the Soviets.
Until WFA came out I had ~30 games as Ostheer, almost all of my pre-WFA hundreds of hours were Soviets. I abused the old button so hard I was accused of hacking multiple times lol.
