FML. Hope another round for essential workers comes later

But in all seriousness, Not actually looking for anything, (I am joking about doing another free code it was awesome to see they did that) just wanted to vent a little frustration, works been rough so please forgive me a little complaining.
Been a while since I could play MWO. Anyone got a list of which mechs/builds to pick up/look into first these days as a good starting place? (played the beta and a little after but have not been able to get the free time since)
Still have a CN9-A, DRG-1C, TDR-9S and a STK-5M from when I was able to play the beta. (I am absolutely sure these mechs builds are completely out of date with whats currently viable. But I'll make them work for now.
Been watching twitch streams and checking out old guide on youtube. Any advice is welcome just looking to play some casual games. (which I'm sure will be disastrous given how bad I most likely am at the game now lol)
