@XxDeepDiveJrxXI'd say that you need to play cautiously with pretty much every hero in this game, because you know, commando droids, rocket troopers etc. that seem to only exist to go after you all the time once you spawn as hero.
Especially saber users are more lor less completey dependant from their abilities as they lack a ranged weapon.
Some saber heroes can be played more dynamically though like Yoda and Luke because heir abilties are all good to fight in infantry modes while with other heroes you basically need to wait everytime that a certain ability refreshes, like Anakin's magnet.
So depending from the exact hero, it's often better to wait behind cover until the abilities have cooled down before advancing to the next enemies.
Map knowledge is very important, if you are new then feel free to explore the map in coop or GA to find flanking routes choke points etc.
