No, sorry, this is a terrible idea to put coils in the raid roulette.
Coils are actually difficult - Back in 2.x (ARR) there was no normal mode and savage mode for raids - Coils was one difficulty for midcore raiders and above. Compare that to Alexander and Omega and Eden normal, which are designed to be clearable by even the greenest of players, and there would be a massive disconnect between difficulty levels. There was a "savage" second coils, but this was akin to what ultimate is today, designed to be extremely difficult to beat and take months for any group to achieve world first, which it did.
This isnt some "Respecc content" meme, but Coils really should be respected for what it was at the time. Coils is still regarded by many to be the best raid this game has had to date, and throwing it in to a roulette would anger a lot of those players. That would be like adding Alexander and Omega savage to raid roulette which, if they're going to do that, would also anger people. Why spend weeks or months at a time learning a tier in one expansion, only for it to become DF content a few years down the line?
Sorry, but yea, very stupid idea.
Haha you gotta be trolling, right?
T1 - Dooable, as it should be, its the very first turn, designed for fairly fresh 50s to be an introduction to raids regardless of previous experience in MMOs
T2 - Has Enrage strat still, but that would also require someone to know about that strat. If they dont? Prepare for your average DF group to wipe for a full 90 minutes on allagan rot and vote disband.
T3 - Erm....
T4 - With Echo, yes this is one of the few fights that can be zerged through.
T5 - Divebombs, Twisters, Adds, Fetter puddles. One wrong move can spell a wipe.
T6 - I dont know why you expect the average DF group to have the coordination required for placing the briars, or even what to do with them, or how to deal with the bees or slimes.
T7 - *Whole DF group gets petrified by one person making a mistake, oneshot by cyclops.*
T8 - The towers actually require cordination - Even unsynced at lvl 80 those things can still oneshot you unless you kill the boss quick enough, and if a lvl 80 in current gear can barely do it solo, i dont know how you expect 8x synced lvl 50's to do it, especially as more mechanics appear with more people.
T9 - Yea...No.
T10 - Heat Lightning, wild charge...Needing cordinated stacking and tanking and positioning should be enough to shoot this one down to not be possible in your everyday roulette
T11 - Once again, needs coordinated positioning.
T12 - I dont know how you expect DF to be able to deal with the puddles, Bennus, fountains and all the debuffs etc.
T13 - LOL
So in conclusion...Maybe 3 or 4 of the 12 would be possible in DF, and also have similar difficulty with echo/nerfs as Alexander/Omega/Eden NORMAL MODE, that's what you have to remember, this is NORMAL RAIDS ROULETTE, not SAVAGE RAIDS ROULETTE. The difficulty has to be similar, or people would just leave if they get a fight that needs similar or greater coordination than your average extreme trial...and if they have to exclude even a single fight from the roulette, then what is the point in adding it? The roulettes exist as a way to find players for old content, if they didn't exist then people queueing for lvl 50-70 24 man raids, or lvl 60-70 8 man normal raids would be sitting in queue for hours. If you want to find a group for old savage or extreme content, that's what PF is for. If they add coils to normal raid roulette, they might aswell by that logic add in Alexander and omega savage to it aswell, because that's old content too of a similar difficulty level.
