100 coruption on cho?

[Ardeth]

Ive killed cho'gal with my guild a few times now and its a pretty smooth kill atm. We've read about 2 healing it, but dont find that we need that, as we have enough dps with 3 healers. Ive seen posts about ppl getting 100 coruption during P1 and then going crazy om dps and i'm just wondering hos that works. Is it just to boost deeps? Or if dps is too low and you would otherwise get too many adherents? Wont you also die eventually and then you save the bress for that and nothing is alowed to go wrong (other deaths). Naturally it seems quite fun to me as I play a lock and SF spamming sounds awesome
Any help, tips, exp or w/e is very welcome

People do this to boost their dps, but it really isn't "needed" bubbles still work on the player(s) so if a priest can keep them up (pally as well) then they can live for awhile.

It's not really needed outside of heroic mode. Honestly, in normal mode, if your disc priest isn't good, you're just making the encounter more difficult than it needs to be.
