Guild Wars 2

However, I’m worried if a decent group can simply manage to avoid 100% of those epic/ dangerous gameplay scenarios. I hope there’s some additional, secondary mechanics that attempt to distract players and increase margin of error, so that timing CC doesn’t becomes as trivial as spamming it on target calling every single time.

I actually expect this to be the only difficult mechanic for the wyvern. It looks like it’s an early instance in the expansion (in the PoI, it was accessible off the starting area), so it’s very likely an introductory boss intended to teach you the new mechanics. Introductory bosses generally aren’t very difficult.

They’ve also obviously thought about this themselves. From the Ten Ton Hammer Interview:

We can do all sorts of different stuff with this and that’s cool. We can add conditions when they’re down, we have a guy that has one non-regenerating breakbar that goes down very slowly over a fight and once you break him he loses his armor and goes faster and does more damage. There’s a bunch of different implementations that we can do with it.

In the above variant, timing the breaking of defiance right would be pretty crucial and not just a matter of spamming your CC when the breakbar shows up. They could also do different things, such as making a boss vulnerable to CC during certain phases (but you’d still have to pick and choose which abilities during that phase you want to interrupt, or how much DPS you want to trade for CC by switching traits and utilities).

More generally, difficult encounters in MMOs tend to revolve around multiple concurrent mechanics. (Encounters that only involve one mechanic at a time generally aren’t challenging, unless they are gear checks, which GW2 doesn’t really have.) E.g. where you need to interrupt an ability, but also need to simultaneously kill an add before it explodes (or does other bad things). In which case each of the individual actions may be relatively straightforward, but coordinating your response to them isn’t.
