Hydra / Death's Dance / Sterak's Feels Too Strong Together

Is it just me or can you build these 3 items together on just about any champion and be really strong?
I've tried these core items on many champions... Riven, Lee Sin, Katarina, Wukong, Nasus, Volibear.. No matter what champion I build them on they feel like they are just way too powerful together.
Am I the only one who has noticed this?
