Dragoon vs Lancer, is there a secret benefit?

[Aratak]

Depending on how buffs interact with each other in this game, there might be some gain you get from Raging Strikes and possibly also Straight Shot (as initial attack for a burstphase).

As DRG it is beneficial to use a damagebuff in conjunction with the piercing resistance debuff. Assuming both buffs increase damage by an factor 1.1 you would get 1.21 (>1.2) when using both buffs combined.
The LNC would be able to set up some crazy burstphases with overlapping buffs, assuming they are all 'compatible' in the way described. Of course skillspeed could really shine in those phases since the applications of buffs (GCD and offGCD) come in a higher frequenzy and an additional attack could fit in the timewindow.
Stealing aggro while not having the backward jump might get problematic however. Blood Bath, defensive CD and a short 'break' using Physique might help then.

On another note:
Having access to 4 different DOT attacks opens up many possible rotations a LNC could come up with.
