I get the feeling that this thread was made partly because of our conversation in the other thread, so I'll offer my perspective:
I'm going to pick two random DoW DPS jobs and go over their rotation. Let's see... VPR, MCH.
VPR: 123 single target combo, or 123 AOE combo. With some variation depending on which button lights up. Occasionally, you can use a different ability that unlocks a separate, harder-hitting combo, and after filling a bar you gain a single use of your 'capstone' combo.
MCH: 123 single target combo. No AOE combo, just one ability plus another that you use off cooldown. Occasionally, you can use a different ability that unlocks a separate, harder-hitting ability, and after filling a bar you gain a single use of your 'capstone' ability.
Okay, two random DoW tank jobs. WAR and DRK.
WAR: 123 single target combo, or 12 AOE combo. Every now and then you hit a different button in your combo to increase damage dealt. You fill a bar to use a more powerful attack, or you use a different ability to use this attack anyway, and every 2 minutes you gain a single use of your 'capstone' attack.
DRK: 123 single target combo, or 12 AOE combo. Every now and then you hit a different button to increase damage dealt. You fill a bar to use a more powerful combo, or you use a different ability to use this combo anyway, and every 2 minutes you gain a single use of your 'capstone' attack.
I hope you understand where I'm coming from.
They can make jobs look as different as they want, and they've done a good job doing so. But, as a person who has played several years, if they stripped all the art and flavor off of every attack and only left the combos and damage, I wouldn't have a clue what job I was playing. Maybe the larger range would give away that I was playing MCH compared to VPR, but you get the point, I'm sure.
(Note: While doing this I did try this with DoM DPS jobs and noted that they are pretty unique, which is why I would guess they are so popular. So, one point for SE. No point in doing it for healers since a healer's rotation is not really set in stone because of healing being reactionary, but I would be glad to go over how similar their builds are if requested)
If I'm delusional, please let me know. But I've maxed all 4 of these classes and played them some besides, and I can confidently say they are homogenized.
