Brand probably is going to be given attention a long time later if he's given any at all.
It's not like he's terrible or overpowered. There are still people playing him in solo queue. Just know that with every nerf to a mage, Brand gets stronger.
And Syndra is almost never played now after her nerfs. Not saying she's terrible, but just back to her original state of never getting played.
I think if they do look at him, they should fix his ult RNG and then adjust its values if it proves him to be too powerful. I also think they should flat out remove his E and add a different ability. Its purpose was probably to just to reliably apply his passive so Brand can follow up with the rest of his abilities, but being instant and point and click, it was given pitiful damage and range. I think I'd even take a small damage nerf to it if its range could be increased.
