How will NIN nerfs affect them?

[HoLoFoNo]

I keep reading stuff like "NIN has soooo much utility" by people when the only reason they are/were in the meta is TA.
Slashing Debuff? SAM who is "Meta" too and WAR who might become "Meta" after the buffs in 4.05 bring that buff too.
Smoke Screen? Nearly every DPS Job can crosskill exact that skill for themself now and even healer/tanks have access to enmity modifiering crosskills... I don't know why they didn't change/remove that ability now in SB.
Shadewalker? Atleast this Skill is somewhat useful but you usually throw it at the Tank before the pull and forget about the ability. (Atleast at the current content) I like that ability though, since it doesn't feel as useless as Smoke Screen.

Don't get me wrong TA is strong but I really don't get why people are speaking about "great/super utility" when in reality it's only TA why Nin is viable.

I'm also confused about the nerf... meanwhile they leave RDM/AST Balance/SAM untouched...

That is because (I presume) you aren't playing at the highest level. You see tanks doing 3k dps on the ex primals on fflogs? (besides padding, most tanks don't get solo balances) This is because of NIN. Shadewalker is always useful since at the current state of tanks, even with the agro buffs, tanks who are pushing very high dps are most likely not using their emnity combo. This means that the DPS that are also pushing their class to their limits are gonna start taking agro. This happens with my group in susano all the time: We have to use diversion on CD and the strongest DPS gets a smokescreen on CD and sometimes it still isn't enough. The thing is, I'm not even playing at the highest level and I'm still feeling the effects.

You could argue it is the tanks not doing their job, but it is also these tanks who are getting the boss to die fastest and if they do keep agro and not die they are extremely efficient. Stuff like this is the difference between 1% wipes and kills or world firsts. The difference between tanks that have NIN helping with agro management and don't could add up to about 100-300 dps depending on how good the group dps is (because if the group isn't pushing dps then there is no risk of losing agro). That is hugh mungus. Trick attack is also extremely busted, only beaten by the like 10 buffs BRD provides but NIN does like 12% more dps than BRD anyway.
