Its a whole faction of Boba Fetts, so to me that make it worth it. And they seem to getting their fair share of new characters in the V-set. Plus the 19 mando with cloaked is pretty sweet from the KotOR set, grab some of those and the cheap Taung from DT.

Mandos are my favorite also, and while i agree they can be hurting with activations. One fix for that can be lobot. His reinforcements allow you to specialize and add activations

I went 3-2 at the Md regional running Mandos. In retrospect, I think I would have done better had I run a Boba-accurate squad rather than the deathshot squad I had, since in my 2 losses I had critical pieces down to 10, 10, 10 and 40 damage but could not put them away.

The pieces I have found the most useful are the Scout (cloaked greater mobile), the Gunsmith (override cunning +20) the captain (grants twin attack) and the Counter-Intelligence Officer. (nerfs anyone with tempo control) The way I play them, I use a lot of mice.

The biggest problem I see playing Mandos right now is that they have no real movement breakers. The closest thing is the basilisk, but they need mice in range to truly be scary and their cost really prevents you from having too much punch in the squad otherwise. A cheaper way to have affinity with Sith other than Ulic would go a long way to solving issues with both factions, although it looks like Sith are getting some help in R&R.

EDIT: At the regional using Jaster Mereel, Lobot and Gha Nacht, no one could out-activate me. That, in conjunction with using the CIO, removed that concern.
