At the moment, the weakest teams in the Europa League are Midtjylland and Sevilla (quite ironically, the multiple winner of this tournament this season among the outsiders), the rest of the clubs are strong and some pairs are indistinguishable from the pairs in the Champions League (especially in the group stage). It is a pity that this tournament has a secondary status and there is no way to fix it, it greatly affects the atmosphere around the games - it is not as tense as in the Champions League.
UEFA make the proper schedule for both of UCL and UEL for an obvious reason, to make everyone can enjoy both tournaments in different matchdays. Both of winners always compete to get super cup title which there were many winners from UEL side. It's a solid proof that UEL isn't that bad. But if we are talking about UECL, yeah that competition status is much lower below both of UCL and UEL.
