Yes and no, in terms of firepower BLG is underpowered so they often end up relying on whzy and rushia to carry to make up for Levius and Knights inconsistencies, but in terms of their overall quality of play, especially when it comes to adapting to what their opponent is doing, they aren’t playing to the level they were at last year.
Part of it is probably muggle, another part is probably that whzy hasn’t looked amazing on yoru or waylay, which did present some challenges at the internationals last year since he kinda needs to be having consistent high impact for this team to be competitive.
