Whats the time frame assuming you are there to start and fill every project fast. It seems to me to be kinda long. Unless im reading it wrong..... You cant have more than one project started. Also its the only way to get to t3. Am I correct?

It requires 32,500 Reputation to get to Tier 3. So doing the 2k project and 800 reputation project, then it takes 20 days assuming you start the projects immediately after they end. Starting just the 2k project every other day will take just over a month.

Wrong math

No one wants a the lowbie set.

Reaching t5 is 26 marks per 39 hours @ 2800 points for 100,000 points = 37.71

So that's 38 times through the gate x 39 hours = 1482 hours or 62 days

... to REACH t5. At which point you will have to first unlock the permission to unlock.
Second, unlock the individual items, third buy every piece and fourth unlock permission to edit it.

So assuming you have 150.000 dilithium and everything else ready, doff's etc. I'd say somewhere over 2 months (we don't know how many days you have to wait for the individual pieces to get unlocked)

We also don't know how many borg marks you need but my first guess is a lot
