you topic title is nin are better tanks now?

To answer that simple questiong i'd say yes they are better tanks now with things such as Yonin and the Blade: Hi if you can get a kannagi or even the WoE version and if you need to blink tank stuff and get af3+2 feet can have 5 and 4 shadows from ni ichi utsu. So yes they are better at tanking than they use to be. But even then blink tanking not hardly needed, just throw a mnk in there with his high hp and a whm can pretty much let the mnk face tank and spam cure V and VI on him and never run out of mp.

Now are they better than say a mnk tank in abyssea? Well i'd say depends. What do you need your tank to do. MNK is the choice of the majority for the tank in abyssea. Can ninja tank this stuff as well, sure, but you will see that majority of groups use a mnk to tank abyssea. PLD's rarely seen in abyssea event groups, they pretty much got stuck with coming slash /nin to the exp abyssea pts and hitting 90 then putting their gear in storage due to being told "we tank with monk so dont even bother coming PLD to todays event"
