I legit don't see how there is little anyone can do. 3 Skyshatter with BH5 will not magically go through guard.
However if WAR removes guard, that's starting to be akin to having a DNC (easier to coordinate with a WAR, just a lot less powerful and far reaching). I have yet to see such premades though, but maybe they're everywhere on other DCs idk. They generally prefer stacking 3 DRGs, or 2 DRGs with an AST for Celestial River.
You're right, we're not at that point at the moment. I'll chalk it up to differences between DCs because so far in every game I have witnessed, premades are a minority, and most people just queue up with the jobs they like. Most BH5 players are also solo players, and while a lot of them sure use meta jobs, a lot also don't, and almost all of them are easy to take out without even the need of having your own counter premade.
That's where I don't agree and will probably never do. I don't see that so called advantage people keep bringing up, unless we suddenly see Guard removal jobs mixed into the deal, which I've never seen so far. And as I said above, I do think staggered DRG LBs from solo players are more dangerous, I personally fear those more than I fear premades, because I know how to defend those, and staggered LBs cannot be all guarded, which means you need to know exactly when to bail if taken out of position.
I've never witnessed those supposedly gaping differences myself. People are blowing this out of proportions.
If your DRK guards instead of doing what they're supposed to do, they can't be guarding and rushing your team at the same time, that's just not possible even with expedient up. If they start guarding once they're already there instead of using salted earth, you already missed your window of opportunity to silence them in both cases. If they wait that long to pop salted earth while making sure to soak silences under guard, it leaves 5 more seconds for people to bail. This is a fail strategy.
Either way, the whole point I was trying to make is that whether there is premades or not, the disaster is there.
