Yes indeed, and that gameplay, where you build up 4 charges of a debuff then drain it off with barrage, is nothing like fire or frost.
It is exactly the same, you spam spell A till you get proc B, then use proc B.
The only thing that is different in Arcane is that you have to use a third spell C, every X seconds.
Is that the distinction that makes arcane special? The fact that it has an extra spell that it mindlessly uses in its completely static rotation? Please...
That is my point.
gameplay mechanics that are separating the specs are just so pointlessly tragic.
You want to see how different specs are supposed to be different, go play a Warlock. Trust me, when you do, you will see how asinine saying "Arcane is different because it must use ABr every 4 AB casts" actually is.
Do not fool yourself, pointing at a single spell and saying "I need to use this spell in a static rotation which is identical across other specs is why this spec is unique".
Its like saying "the only thing that makes Destrolocks different from Affliclocks is that Destro uses the conflag spell".
Which, as we know, is not true. Affliction and Destro are completely distinct, far above and beyond just which spells they use. That
is the quality of variety I am speaking of, not a "look I have to use this spell as Arcane so I am unique".
Again, let us not fool ourselves here. Looking at the reality of the issue is the only thing that will help us help the specs and classes that need it.
