Best 4rd and 5th for Darth Revan?

[scenic mountain]

I am currently working on Darth Revan and Malak. My team will consist of Darth Revan, Darth Malak and Bastila Shan (fallen). Who are the most ideal 4th and 5th on this team?

My thoughts are Sith Marauder and either HK-47 or Sith Empire Trooper.
HK47 would be more efficient since I otherwise have to collect two toons from scratch with cantina energy, which I will also need for relic materials. Plus HK-47 is already at 7* and G12 for the Malak journey. But if SET is the absolute better choice than HK47 I can take this into account.

Ps. I don’t have PG unlocked yet so Malgus is a long long way off and is not needed to take into consideration as of now.

HK-47 usually rides the bench. SET is absolutely better. Eventually, SET can be replaced with Malgus or even Talon. As a tank, SET will be helpful on that DR team. HK just kinda sits there. You already have enough damage dealers.

HK is a better 5th until Malgus. Maurader ramps damage and durability with the buff/debuffs. Malak should be able to tank most everything that you counter. HK will land more debuffs (Maurader), has a special for major damage, will more likely trigger deathmark under DR lead. Save for offense and you don't really need a second tank. SET is just luxury second tank / will be set aside for SEE/Bane/his ship

I wouldn’t build HK-47 for the team but if you have the LSB by all means use him. DR/Malak/BSF/Marauder/HK works well enough. Can realistically swap Malak (have him solo) with SET on weaker teams though since the DR team tends to shut down the enemy under debuffs and you just need a tank rather than an amazing tank.
