As a healer/DPS these are generally the ways you can use bop in keys. As a tank there’s a bunch more, but we’ll skip that since it isn’t relevant to the post.
On a tank:
Never, except in very niche situations if you’re in voice coms.
On DPS or yourself (healer):
- To prevent taking dangerous physical damage (a lot of trash aoe is physical). I think the charging rhinos at last bossin ToP is physical and can be negated by bop, can save players who are bad at mechanics.
- If a DPS is burstng and risk stealing agro, bop them to let them burst without risk of death.
- If a DPS/you got agro and tank won’t recover it before you get one-shot.
- When someone gets fixated (small mechanical bots in floodgate) and risk death because they won’t cc or move slightly.
- To clear bleeds, for example on second boss in motherlode when people are bad at kiting.
That’s the most basic things I got for now, for the advanced things you need to communicate whilst playing.
