Is it even worth to run blueprint with the ex trinket? Currently it cost 100 chaos worth of rogues mark to run a blueprint for me(using 3x gianna on wings and normal reveal on rooms).

You can get rouge markers rather quick in high tier maps, so why buy em?

The trinket can be worth it. If you are using Vinderi for the double currency chance and the exalt from trinket goes off at the same time its double exalts.
You can get em without he trinket too though, so preference I suppose.

Currently sitting on 100k rogue markers and i cant get it done to get below that figure. it is only growing
So dont bother buying them.
Easy steps:
1 Run maps: get contracts (and sometimes a blue print) and low drops of markers
2 Run contracts: get reveal points and high sell value of markers for the contract item
3 If enough markers and reveal points to reveal all on a blueprint goto step 4 else step 1 or 2
4 Reveal all on blue print
5 Run blue print and get what some say are "the really good items".
6 If enough markers and reveal points to reveal next blue print goto step 4 else step 1 or 2

I dont use a exalt trinket and already have 4 times the amount of exalts that normally drop in a league and still 1 month to go
