Ancient Sentinel

My vets finish promoting to R5 tonight, thinking about trying with them, R6 megas, R6 treb, R5 radio tech and R4 Elemental...wise...or unwise?

Your RT, vet and ET are one rank below mines. Not sure you will be able to do it without nanos. But I think if you don't have a formation that is working fine it's worth a try.

Figure the ET is there just to freeze the arm and then it doesn't attack again right? So I could use that or R5 cryo trooper...

But it's good to soak damage too keeping front line alive for more time cause sentinel will split damage between ET and vet.

Are you guys kill first both arms or just one.
I kill just one because I read on BN forum that there is bigger
%chance to get fragment.
I have to level my Veteran anyway.

I've attacked the arms first and used 20 nanos to keep two megas alive! But won, I think the arms are waste of time, jus personal opinion, but I just used 8 r5 megas and 2 tks and only one mega survived! No frag either!

The sentinal is complete BS. I just hate how it stunlocks everything. Due to this i now wasted 24 nanopods! The AS now always hits the veteran.

You might want to try 3 veterans in the front row. It just respawned for me today and I tried it with 3 vets in front. ET, Treb and 2 megas in second row. RTech and 2 megas in last row.
No nanos needed for healing and the survivors were 1 vet and 4 megas.

Another kill and no fragment only good news no nano waisted. Formation Vet (r6) Cryo(r5) X X Vet, second row Megas (r6),third row one Mega, RT9(r5) and treb(r6)
