It seems like just about everyone, now that subclassing is a thing, is running some build that pulls you into a colossus hit. I swear, in any given hour, I see 100 attacks like this, especially on DC.
The attack pulls you into the center, stuns you, and then the colossus pounds you. Its even worse if they have Viscous Death.
Other than Nibeney, which only helps so much, how to you counter this attack? You can't dodge roll out of it. In fact, I've done so, and have been several in-game feet outside the area of damage that shows on the ground, but still get pulled in. People say "Block", but most times you get pulled and stunned and can't block, because first you need to break free from the stun. By the time you do that to block, you're dead.
I'm willing to say that 80% of the kills I see in PVP are from bombs.
