I am not so sure of that, what I meant as variables was the options in the game, Raiding PvP, 5 mans etc. In other games you had one toon with either one or two spec options depending on the game. Here you have up to 4 roles with 9 souls, will there be certain souls that are needed to make a viable spec I am sure but I don't think people are going to copy so and sos if theres is performing just as well.
I mean the whole warriors are the only tank in 9/10 games just went out the window, Riftstalkers can tank just as well and they are rogues, splash heals from a Marksman/Ranger/Bard might be the difference between winning and losing an encounter, while still doing great dps. I don't disagree with totaly with you but besides the hardcore raiders which are sually only 10% of the population people are not going to change what the enjoy doing if it is 95% as effective
