that is not easy mode and you can't do it with bad players. Not to mention can make T5 harder for some people, divebombs going when conflag is up is a prime example.
That happened even before Echo (and it was even worse then). It's all based on when you damage Twintania into the divebomb phase and it only takes 1-2 attempts to figure out how many conflags will happen before the phase change and you can plan ahead. You can even leave the person in the conflag as if she goes away for divebombs it's very likely that it will stay up for quite a while. The first time we beat T5 we had someone in a conflag and our BRD actually solo'd it down from about 1/2 hp while we were avoiding divebombs.
