The m8a1 gmc is worse than the tech tree m8, giving it access to the APCBC rounds would make it more comparable. With some better ammo I might find a reason to use it.
When compared to the tech tree M8, the M8a1 has:
I would hope that the M24 also gets access to APCBC, I really dislike using the solid shot rounds.
Only if Chi Nu( or Ho Ni III) is moved to BR 2 aswell… especially the M24 would have no downside compared to the japanese tanks
Or they are moved back to BR 3 to compensate for the buff.
I wouldn’t have an issue with the HO-Ni III on BR II. That tank would be trash. 
And why would the Chi Nu be better than M24?
Equally bad armor
Worse faction to face so it has a worse gun coparatively
No viable mgs to use.
Less mobility
Shermans are now competitive and on par (ammunition wise) at all levels!
Immediately: “Not good enough! Gib moar!”
Strike while the iron is hot
It was forwarded, but as usual the decision is up to devs
Will then the Chi Nu be moved into BR2 aswell? otherwise US would have better version than it but in lower BR or alternaively move the M24 back into BR 3to avoid that issue.
