I leveled 5 Bards to around level 13ish. I like the synergy of all bards! 5 ended up being a little too much for my PC atm. So I'm doing 4 for now, and 4 is very smooth on low settings. I have my main turned up a tad so it looks better. I have won 7 out of 8 WFs so far. Stacked bards are OP and i would not be surprised at all if they nerf them soon.

Not sure what i will try next.
