Wouldn't it be better to give BRD support LB instead of heal LB?

Hello,
I know that most of BRDs would love to have DPS LB but I think that isn't going to happen in Frontlines plus I also mean that BRD as support role is nice too, even in Frontlines.

But why can't we rather have some support LB.. for example 10% damage buff + healing done for 15 seconds for our party? It is just my idea I was never good with stats and theory crafting but I really think it would be much better to have something like this.

If you think that my idea is bad or you have a better suggestion feel free to leave your positive criticism, please. :o

i remember readin somewhere yoshi stating we would be gettin a dps solo LB dont know if still planned or not but the 2 healing Lb for bard are just zzzzzz
