Can someone please explain to me why exactly flame on is supposed to be so increadibly amazing?
All I can find is that if you incorperate it into your combustion rotation it is somehow amazing, but I don't really see the difference. Without it I can also fairly easily maintain the Pyro spam during my combustion, so what exactly does it do that makes it so increadibly much better? The most I can make of it is that occasionally (like once in every 10-20 combustions) I'd like 1 more fire blast for 1 more pyro in the last second of combustion and flame on could give that. But to call that amazing seems to be stretching it a bit.
Also, it seems borderline useless outside of combustion. Since you can't use it while casting you need to interupt whatever you're doing to use it. But more importantly, it's only really usefull if you have a heating up proc and have more than ~2 seconds of CD left on fire blast, since if it's less than that you can fit it in with your next fireball cast, which doesn't happen all that frequently either.
So all in all the best I can make of it is that it might effectivly give me a handfull of extra pyro's over the course of an average bossfight. But that isn't exactly mind blowingly amazing, and controlled burn looks like it'd do the same, and over the course of an entire bossfight the difference in reliability is neglible. So why do all the guides keep going on and on about how this is somehow the best talent to have ever existed?
