Aren't we going towards a dungeon deadlock ?

I don't understand the issue? What grants Law now will grant Eso in 3.2. So gearing will be much faster then it currently is? You can run Fractal/Neverreap/Roulette to get Esos at i145 jumping you to i200.

If we follow the same trend, no you won't.
Sirius and Arboretum will be pushed back into lvl60 roulette.
To unlock lvl 60 roulette, you have to do all dungeons in the roulette.
Sirius and Arboretum require ilvl170.

So, to unlock lvl60 roulette, you'll need to reach i170...without law tomestones.

When we get a new currency, Eso will unlock. I don't think the Law gear will go away.

Eso will unlock because they'll become the lowest lvl60 tomestone, thus, at the same time as the removal of Law Tomestone. At least, it has always been that way until now.
The only exception is Poetics and it's thanks to the level cap increase.

And the existing dungeons already drop better gear than Law.

New players could choose to run Fractal and Neverreap without the roulette to get Eso tomes. The Eso payout will likely be increased once Eso is the lowest tomestone.

I'm guessing the old law equipment will be added to the Centurio hunt vendor to help keep it relevant since Centurio seals weren't used for new the relic quest.
