Didn't you answer that yourself?A "grid" is more than just a bundle of SSR and SR weapons. Gathering them up is not that hard, although raid events are a pain in the ass if you don't get lucky with Gacha. Thankfully, that's getting fixed the very next raid event.
Anyway.
The next step is leveling them up - and this is where the weeks and weeks of the extra hours comes into play.
I don't think Sanathlig said anything about you not gathering weapons. Let's take a step back.
This is what started this:
As far as I can see, there wasn't anything about skipping events entirely at any point. That was just you shooting off a tangent into a random direction.
The point is, for those who don't want to spend a ridiculous amount of time on the game - not something I want to do, but hey? - they can focus on just one element and be able to use that on all or at least 5/6 elements. As far as time/effort goes, that's by far optimal, wouldn't you think? Of course, putting in six times the effort WILL make you more powerful. Although this gain is largely gimped by the fact that you're not going to have a proper team for these other five grids. Somebody who has collected all the Thunder SSRs event weapons is certainly NOT going to be able to clear Water Accessory T4 with just random SRs if the weapons are like slvl5 or 10...
And speaking of going off random tangents, god. I'm not going to untangle that mess you two made in that other topic... both you were going all over the place.
