Considering you have a BLU skill called Basic Instinct that lets you practically solo any dungeon that it can do today, it doesn't matter.

They already gave people a challenge in doing older savages and extremes sync'd with the kit you have, and you really do have to work for them. Basically the same mechanics when they were relevant with some twists now that you have diamondback and anyone can frog legs and tank if-needed. If anything I found this aspect the funnest part of BLU. Doing what you were previously taught just in a different way, sometimes easier, sometimes not. Like mechanics that were designed for only tanks or healers with normal jobs don't apply to BLU, anyone can get the mechanic(s).
