This last weekend while I wasn't able to get much done in game due to real life stuff, I did finally get to do Posi and Synapse. Great fun was had by all, minimal deaths, mostly mine on the Posi. Didn't realize the large amount of -rech that early in the game. Vahz and CoT both di there fair share, as well as the bosses from the Lost and their psychic powers.
On the Synapse things ran much smoother, except for the end drain.
With buffs from teammates, I was one of the more durable melee toons, but there was no stopping that -rech.
Will update during the weekend.
