yes or no
just lvl 5 i dont know
most cases no.
Sometimes yes. I wouldn't get it until my 6th item, however, since the wasted gold on the mana can hurt you early on.
however in rare circumstances its debateably good, due to the health passive of catalyst and the shield if their team is ap heavy
Warmogs gives you more effective health, just buy warmogs.
Quicksilver Sash does similar things, for cheaper, without wasting money on mana.
Usually most people get QSS or GA for manaless champs as a defensive item but BV is an ok item.
Won't kill you, but there's usually a better option. It's like Sheen/TF where it has mana, sure, but that isn't the reason why people get it.
