If by slow toons get damage increase you meant less than 100 speed then what was said is true, otherwise it was a lie. The biggest damage dealers that are fast got the least damage reductions while slower toons that already did low damage got bigger damage reductions. Magma barely did any damage before the update and now he isn't even usable. Why reduce Barris of all toons? Slow tanks got reduced, Anakin is dead, but Rey can still do 10k damage in one shot. Qui-gon can still remove positive and give offense up to whole team and do about the same damage as Mace can with his special, which doesn't give anything, bc his special damage was nerfed, and he is 1 of the slowest toons in the game.
The meta is still the same. I still see the same teams in arena bc they are still the best toons. It's like there was no real balancing, just an attempt to make games last longer and challenges harder. Why would it be said that these fast toons would see reductions in damage but then reduce almost every other toon more than them? I am truly stomped on this matter. Go to SWGOH.gg and look at what was done. The balance was reduced.
