The way I look at it is.... which one are you more used to? I played 1.0 so, I am more used to Legacy Movement. People who are used to the more WoW type controls probably are used to games that use that setup. As long as people are dodging who the eft cares?

Though, I think with Titan (Hard) specifically you should try out the Legacy Controls for weights in last phase. It helped a lot of people I've suggest this to, but really only in that particular instance.
