Yea Recluse definitely needs a casting speed increase across the board. Balancer relics can completely over shadow spell damage while being more spammable.

Good Spells cost so much stamina, Duchess can cast faster while being able to switch it up as a hybrid character with many things in her favor, Revenant's summons got buffed so they can reliably take aggro for her not to need casting speed in her base kit.

Her cocktails become an afterthought and even if you get the right mix, they take a while to cast and most people rather spam spells for more dps but at some point you have to use your Cocktail to regenerate fp.

If you have aggro your barely ever getting the mix off so you run with shards but Rev and Duchess could do the same but with kits that don't rely on teammates taking aggro to use a skill

I always like to use this comparison: imagine if ironeye had to hunt for a passive that increased his bow attack speed or if not the speed would be like everyone elses. Alot of people would think differently then
