Nice theory but I think that control is just another form of support.
For those interested in this kind of analysis I think you should start focusing only on Damage/Support, there isn't any other thing than that, and yeah those two relates somehow too, but control is too redundant.
I blame the old trinity on this ^^ for me, now it all comes down to damage and support, just that.
I do understand your point, though personally I see it as Damage/Control, which is only a difference in semantics. Essentially, it boils down to the fact that you have to draw the lines somewhere when you are discussing any given topic, otherwise you can make a roundabout argument about almost anything and talk yourself in circles. I do acknowledge that you can use your control skills to assist (support) an ally. Again, it comes down to semantics which is why I defined them as I did:
Damage is well, damage without any ancillary effects.
Control is effects directly applied to opponents to hinder them.
Support is effects applied to allies to strengthen them.
These are by no means
the only way to define roles in combat, but they are the means by which I was analyzing the professions. There are many others such as utility, range, sustainability, etc. The reason I chose to define them as such was that control and support as I define them are essentially perpendicular effects. If you apply control to one guy, it doesn't help your ally very much if 3 other guys are wailing on him. In this case, giving a supportive boon (or protection) will make him more effectively able to withstand their attacks and may cause them to disperse. However, that one guy that you controlled is faced with no good options individually because it doesn't matter who he attacks, it will be worse off for him because he his being controlled. Control effectively is better for screwing one guy than protecting one guy (unless you can do large area control which there is not much of for the stronger conditions). Support is better for protecting one or more people regardless of how many are attacking them.
Obviously, there are some exceptions like large area control, but I think you will understand my point. If you have to choose between what I define as a single target control or single target support skill, they have different amounts of utility based on the situation. I hope that all makes sense; I tried to define them for the sake of my article's purpose rather than to say they are the only way to view such things. I think setting up guidelines for a piece of work or theory really fascilitates discussion. If this isn't making sense, blame the fact that I just go home after driving 5 hours :zzz:
