Just wondering if it's worth it to fill out for stormcrow or timber wolf, as I have one of each now....Sorta realize that it's tough to necessarily go wrong either way, as I did get an ACH last weekend as well. Or have I answered my own question, is the finishing question, lol.
All 3 chassis you have mentioned are the best chassis in the game for it's weight bracket (arctic cheater vs Firestarter from IS maybe tied), so actually having all of them will be very usefull, especially if you want to go further with your gameplay and join Community Warfare. For drop Deck you can go with TBR, TBR, SCR, ACH, You can also go for Hellbringer and Ebon Jaguar as they are also very good chassis, but i would treat those two as complement to the first three mechs.
TBR, SCR, ACH. As for assault either DWH or WHK, but that is not important. EBJ/MDD is also ok if you want a secondary Heavy, or HBR for ECM.
