Tier set woes

I don’t have any charges left to convert newly obtained conquest gear to tier gear. Should I just wear my PvE tier set and wait or should I wear the conquest gear and say f it and go without tier?

Or should I swap out of my PvP healer and get a weapon and use it for ret. I like to play different characters of the same class rather than swap specs on the same character but if that’s the better play, that’s what I’ll do.
