Pfft, normal mode, most of the skill mechanic in the game can't be fully enjoyed if you don't play on inferno mode.
Dragon is easy to counter since it likes to jump, if it throws the meteor thingy, I step back and counter that one. 1 to 3 counter (depends if king fisher activates or not) then start the aerial combo. The dragon is the easiest mob in that dungeon.
Sword armor has two attacks, the stab and dark thingy, the pulled arm animation is a bit different. Stab, wait half a second. Dark thingy, it has a clinking sound, wait until the sound end to counter it. I can't pull the counter with it perfectly so I just hit it a few times with hit and run tactics until it guards break and start the aerial combo. Wind Slash, Raging All, T Slash and Swoop Raid depending on the position and height until it dies.
To add more against the armor sword giant, start with the dash hit. Back off until it attacks then start the 3 hit attack hit and run. At hit 15, the guard will break so start with Wind Slash and keep comboing.
