Yeah but the main disadvantage of using turr with PTL is you are not as high in pilot skill so you may not be able to arc dodge before getting shot all the time.I far prefer Turr Phennir + PTL to Soontir Fel + PTL
Both get 3 "actions" per turn, but one of them gets two actions in Combat, as opposed to just in the main phase.
Yes, Fel can get 2 focuses in a turn if he really wants them, but I'd prefer using a boost/roll combo to get fully out of foes arcs while still getting to use my focus offensively.
Plus Soontir's name sounds cooler
If you are really in a jam, just use PtL on him when you normally take actions. It's not like you have to use his card text every Turr-n (pun intended).
In short, Fel and Turr have different uses, you just have to play to their strengths.
