Ok. So, fresh dinged to 50 (or well, almost fresh), I'm preparing my character (aka playing through msq) for Heavensward that I was thinking of buying soon.

But... I was thinking... I'm not sure, now that Heavensward is out, is getting relic weapon a necessary?

I read that most of MSQ and dungeons expect you to have it and that MSQ requires item level at least 90 or above, so... it's something you really can't just "skip", isn't it?

So should I start relic weapon quest and wait til I get it done before continuing MSQ?
I also heard you can just buy i100+ gear from Ishgard? Meaning basically there's no point for me to start gearing up besides what MSQ requires?

I'm really sorry if this sounds stupid, I'm just really confused about it and all the guides I found are for old patches and/or gearing guides.
