Why give us catalyze? So we could place it on people who aren't tanking and then have to heal everyone up anyways? Overhealing that one target for the whole value of the catalyze in the process? "Come on".
Catalyze wasn't something "given" to us; it's simply something that makes the doubled barrier from critlo not spreadable due to the fine print stating that DT only spreads Galvanize, presumably because they thought being able to spread a full strength critlo (particularly since now you can perform one on demand) was too overpowered. I'm not really sure what else you're trying to get at here.
