IF you don't have to run into triple Scouts, or double w/Party Bus, you can win plenty of games with T-70s. If you aren't that lucky? Say bye-bye to any sliver of a chance at a positive win loss ratio. At least that's been my experience thus far. The Contracted Scout is pure poison to Rebel small based lists. Full stop. I wish it weren't so, and it will take a damned big change for me to forgive FFG for it. How they missed it in play testing is beyond my comprehension.
But! You can still have a ton of positive gaming experiences against everything else. The T-70 is fun. It's shooty enough and maneuverable enough to give you a chance even against Palp Aces. Why? Because they can't evaporate your ship and still have the firepower left to cripple another in a single round. Bloody hard work is required. But it's worth the effort.
There. My 2ยข has been added to everyone else's. So fly the T-70 and just accept that Jumpmasters own your ass.
