I think the Seraphim T3 sub hunter has been changed and is now much stronger than it was before and is now over powered.
I think most people don't know this so they don't take advantage of it (so far) which may explain why there aren't more comments about it.
When someone does take advantage of it though it ruins the game for their opponent.
Could the relevant person please reduce the sub hunter's strength to bring it back in line with all the other units.
