Now, in terms of the Marauder/Sentinel, are they melee strikes only? As in no type of CC?
There are slows and immobs.
No hard CC. No stuns.
If you want lots of CC, go either Smuggler/Agent or Consular/Inquisitor. They get lots of CC and a lot of other utility.
Marauders get Force Choke, which is like a CC, but you have to channel it. Not counting that droid only CC.
As a Marauder, you're purely DPS with minor self and group buffs. Like being able to increase movement speed by 30% and ranged/melee defense by 10% for a short period of time after building up 30 fury.
Fury is a second resource you'll have to keep an eye on.
