SAM out classing all other DPS

[GunZLegend]

it really isn't easy to get high numbers, esspecially when theres a lot going on.

You can say this about literally any class in the game. The difference is fundamentally how a class is able to deal with it as well, to which you can make your argument. SAM has plenty of things to deal with down time, and never has an issue with resources unless you somehow can't keep up with it(to which the argument is how bad your awareness is.) You can never lose Kenki or your Sen because of mechanics, and even if a fight were to somehow disrupt your flow, Hagakure converts your Sen to more Kenki, which is never bad unless you have an overflow (You should generally be in the position to where you shouldn't) and puts you back into neutral and also helps you avoid overlapping sen when reapplying buffs and DoT. Your buff durations last much longer than many of the buffs in the game that demand you to maintain, to which MNK players will smack you for not appreciating considering they have to manage GL in half that time, and also can't convert them into another resource. Neither can DRG, and NIN dodges a bullet slightly considering their long duration on Huton as well as there is very little in the way of recasting it should you need in the moment it is unavoidable, or gauge whenever your CDs will be coming back and so you can just reapply Huton back to 70 seconds and have your mudras ready when you get back.

Your DoT is a full minute and thus is easier to keep an eye on compared to other things such as demolish and Chaos Thrust, even in the midst of mechanics.

All of these examples come from all of these jobs going through as much of the same thing as possible.
