Well, the alternative is randomization of mechanics, in which case you need to make sure they are still beatable even if RNG decides to really eff you over. After all, a boss can't do more than he is coded to do.

Plus, any reaction time check is affected by latency, so testing that is often more of an internet provider check.

So yeah...they could try around a bit more with the randomization, but that's really all that works well in an MMO setting. It's a bit more effort on the dev part, but doable.
