To the first: I also like when buttons pull double duty. Gives us more abilities without making us need a dozen hotbars to use them all. I'm not sure if things not lining up is a good thing or a bad thing, honestly. The more things line up, the more generally manageable it is and the more things line up with the 2 minute window (which is what seems to be the design objective at present). For example, my biggest complaint on GNB is that Bloodfest's CD lines up with literally nothing else other than (SORTA) every third Gnashing. Which doesn't really feel good at all.
To the second: I mean, if we want to carry through on that, why stop there? Why not just go ahead and leave all the Jobs just as they are today to prevent that complaint in the first place?Sarcasm aside, I don't think WHM needs anything to "prevent" that. People are literally going to complain about anything. I saw a complaint thread in here a few days ago about someone not liking Sage's combat stance, and in the discussion, some people mentioned they don't like its Sprint animation (which it shares with PUG/MNK). People are ALWAYS going to complain about SOMEthing. I think when they consider the solution is "things as they were in ShB/EW", it'll silence most of those complaints. We needn't make the ONE Job we're keeping simple more complex to satisfy the people that will, at that point, have exclusive claim to ALL THE OTHER THREE Healing Jobs, I don't think. Again, is the objective to allow bored people to have options for Jobs to play and be less bored, or is it to force everyone along for that ride? The first I will support, the second I will not, and I'm hardly alone.
To the third: If they didn't want to "graduate", then they wouldn't have a problem with it staying easy, would they? And if they didn't like it being easy, they'd "graduate" on to one of the others. I get what you're saying - some people might decide they really love WHM and want more to do on it, specifically. But you have to understand the contra position is that the people who like simple are already having THREE Jobs robbed from them, and you're insisting they also give up the fourth. Can you see how that wouldn't go over well? It's not a win-win. It's a win-win-win-partialwin for the people complaining now and a lose-lose-lose-semilose for the people who love healing as it is right now. See how that's a problem?
EDIT: And for clarity, remember that many people who like simple playstyles are already playing some of those other Healing Jobs. You're asking them to not only give up the Jobs they love, but entirely give up the playstyle they love as well by not allowing them even ONE option that they can enjoy. I feel like that's not a viable solution nor is it a compromise position. Granted, the Devs probably aren't going to change ANY of them, but we'll see closer to 7.0, I suppose.
