Returning player, looking to try Melee DPS

Dragoon is pretty bland and dry in the early levels, especially at 50 where the only thing you're really doing is the same 1-2-3 combos, making sure your CT dot and piercing debuff don't fall off, outside of that it's just weaving in your 3 jumps while keeping HT up. Dragoon becomes way more fluid and smooth once you get your Lance mastery trait at 64 that let's you use both your 4th tier abilities back to back which means more frontloaded damage and more botd uptime. At 70 it's incredibly fun and rewarding to play, you'll never get bored with how well everything flows together.

So 1-2-3 is "bland and dry", whereas 1-2-3-4-5 is "incredibly fun". That seems odd.

Can you by a chance compare your results from Savage and EX fights to other dps?

Savage Omega fights does not disturb the rigid rotations?
How does fights like Shinryu treat positional attacks, when the boss is facing you with front all the time - is this somehow addressed by devs as for example that Shinryu's hitbox is treated as "all sides" at once?
[EDIT] - as some other posts mentioned, this is likely the case (Shinryu has no "different" sides)
