In Titan, you only have to worry about 1 thing at a time, (his rotation is script).
but in coil, espically Turn 2 require multitask of everyone in your party (mostly, may exclude malee dps). Tank will be require to take turn taking boss and dodge red circle and take turn silenting the boss(unless u got 2 BRD). all range will have to dodge all the red and passing the rod (healer have to do all that and keep tank alive as well ><).
