Leviathan's Wipe at 20%?

[Raenryong]

Mercy stroke is available to all melee and tanks, misery's end is available to archer. Yes, SE's intention is to prevent parties of all casters. Do you have a problem (regardless, both tanks have it so you make yourself look like an idiot)?

My problem is that all DPS do not have access to the information required to moderate their DPS. As I stated earlier, if you stop DPS only when the 20% thing lights up, there is a good chance that remaining DoTs etc will push it over the edge.

Having to rely on tanks for the information required to dps is poor design in this instance. To use an illustrative example, it would be like if a mechanic similar to Briny Mirror had information about it which was only displayed to two DPS or similar, so the healers had to rely on these DPS to tell them when to stop healing (or they'll wipe the raid instantly, in this example) - and god forbid they have Regen or Whispering Dawn running...
