Fire Demon or Mana Relfection?

That's not too wise of an outlook, especially if we know certain skills will see beneficial changes in the near future. End-game should always be the goal of high levels, and as it has appeared reading this thread, Fire Demon is definitely the best choice. I've had both maxed at one point or another, and decided to max FD over MR with the full SP reset given at the onset of Big Bang as the added DoT damage is just slightly more beneficial on an average basis than MR.

The thing with Mana Reflection is that, as stated earlier, it doesn't kick in very often - only 60% of the time and only on magic attacks. I know I'm reiterating the obvious, but it's something you don't feel while playing until you have it maxed and see how pitifully helpful it actually is. If the skill worked like PG with ANY damage received, reflecting at a 60% rate, it would be the no-question skill to max, especially now that it reflects a good 1000% of damage at max. But the bottom line is that you'll still have some points in MR at Lv. 200, and as the difference between that skill's effect (I believe my MR is maxed at 11; I think you're off by 3 points saying one will be Lv. 14 at max) and what MR can do at Lv. 30 is important to note, it becomes clear FD DoT damage at max is much more helpful than max MR.

But, of course, neither help by much.

We're getting SP Resets when the skills are changed, so I'm thinking in the present since Chaos Update is still a few months away.

But I see what you're saying and I guess FD is the way to go.
The 60% Success rate for MR was the only thing making me not like it. Plus nothing really hits very hard anymore for it to be able to deal large amounts of damage, so it does seem pretty useless.
