Are Orange items only found in level 4 lockboxes?

I have bought piles of level 2 and 3 boxes and have gotten nothing but garbage. Do i need to spen 64 keys on a level 4 box to get an Orange item?

Some people said they got from Tier2 and Tier3. Seems some get more lucky then others.

I buy t3 and get some pretty good oranges

Welcome to the MMO world with totally random loot :) Good luck though.

17 T3 with no orange while my friend who is only 350 rank has 2 oranges.

Yes. I've never actually bought a t4 box. Only t2 and t3. I have an orange sniper and lobber. Ego 350.

Wait oranges are rare?, oops. No wonder I got lots of ark salvage for them ROFL. xD

Personally I got equally lucky with T3 and T4.
However, I spent a lot more keys on T3 boxes. While your number of items you get per key is twice as high with T3 it is T4 that has a higher chance for orange items per key spent.
I never bought T2 though, odds for purple and orange items are not very good.

Since the patch I've opened 5 tier 4 lockboxes, 1 didn't give me anything at all (it glitched), and then on the next 4 I got 11 blues and 1 green. That is poor.

I've had 6 legendaries before the patch, get nothing but crap now.

I got my Legendary Shield with +75% HP Regen out of a Tier 2 Lock box xD
