I actually did rank all the way to 15 before properly farm Castrum and honestly, at this point I think was not a smart move because I skipped successful Castrum runs.
But as more as time goes on, more people get famililar with Castrum mechanics, making runs easier? At least that's what I was basing myself on. So far I've been through 3 Castrum runs that failed in different points of the raid, mostly due to people being completely clueless on what to do on those fights...
