Or...if you have alts: 
In pursuit of those very rares to make t-4's, often I end up with achieving vet levels that continue to award emp merits. Once you get 30, you can convert to a very rare. However, often, a character may be used frequently once these t-4 goals are attained, and then you have surplus emp merits. 

Totally up to you, of course, but I like to send a transcendant merit to my next 50 - so that once they unlock lore and destiny, they can become +3 right away. I ignore judgement & interface. I only use shards for alpha because it just doesn't take that long to get 4 shards to slot t-1. The weekly will give the notice, and you can use threads to craft the t-2. (or break down emps if you are really desperate - not recommended) 
An MSR or three will go a long way to unlocking lore and destiny, and you'll often get the shards you need to make that alpha t-2. If not ,there's always the thread option. 

This way, you can be +3 by vet level 3. You won't have judgement or interface - but you've gotten along 50 levels without them. A little while longer to open the gate to the higher level incarnate trials is worth it to me. Not for everyone, but it's just a suggestion.
