Again, bad class design only makes things harder if you have complete control over what happening. During phase changes, you don't, you did what what was possible. At a certain point, It's out of your hands.
Again, Drg is out of luck by poor design, Mnk now has RoE to extend GL and still has PB. That's also why everyone tries to dump everything before phase changes etc. All so you can start "fresh" upon boss return. You are right, Sam doesn't get hit as hard as Drg during phase change, neither does Nin, or Mnk now for that matter. If everything is dumped before phase change, the all of them have to go through their buildup phase again.
60 potency per positional, but yea that's a tough spot for drg. My goal was to inform people that the positional does matter for samurai. People seem to be unaware of this since the game does not explicitly state it.Also lemme answer your scenario with a scenario: A10S with it's plenty of mechanics forcing you to move, along with the boss moving beyond tank's control, and a bound mechanic that will keep you from moving or even turning. You won't have True North for all of that. From what you said, SAM will only lose 60, meanwhile you have DRG still losing more than 100 should you proc FnC followed by WT out of Chaos Thrust. God forbid they have a boss with all of that plus A11S with forcing people to hit from the front to break a shield. In that situation with no True North, SAM still doesn't miss out on much.
I would say it does reward you for good play, even decent play. I still don't see where the rotational difficulty comes from other classes. GL and BotD at this point are practically passive and you will/may loose them during phase changes. I don't see how that alone makes those classes any harder. You will try your best to figure out how to keep them going just like a sam is going to try and figure out how to best use his kenki and sen gained for the phase transition. They're different but the end goal is the same.. to keep dps rolling.I love SAM as a class and for the aesthetic since I wanted a sword wielding DPS for so long, but let's face it, it is easy as sin and rewards you way more than any other class at the moment. They had more thought into them and it shows.
