-Do not parry Wildlife, instead doge/evade them and hit when openings occur. You can also hold block most of the time when fighting them. just strike when their animations are done. (You can parry them, but evading can be more easy)I really suck at the combat in this game. It just doesn't click with me. Even on easy it's just embarrassing.
-Double bladed LS is awesome in getting rid of groups of small and weak enemies. Normal LS deals more damage, but is a bit slower. If you are having trouble to sidestep, just role.
-When deflecting normal, ranged storm troopers keep the block button pressed till they stop shooting. It is possible to deflect every single shot from a burst but it is easier to just deflect the first one back and just let the rest bounce of from your block.
-You can skill auto block ranged attacks while running. Very useful to skip past melee troops and reach the range ones.
-The strong attack (Y) is your friend. It costs force, but it is able to break through most enemy defenses pretty easily. Especially the upgraded single LS version.
-Force push can also be good in breaking enemy guard. All together do not forget to use force powers whenever possible.
-Many enemies can be "body pulled" away from their groups. Just run around a corner and wait for them to come one by one.
-Rockets and grenades can be tossed back at enemies with force push.
-Look at enemy animations, they don't have many attack patterns and repeat the same 2-3 over and over again. It's sometimes best to just let an enemy attack you for a while to get a feeling for what he is doing. It's kind of a learning experience.
