Unfortunately, that "meme" can not die unless DRK and WAR are getting real unique designs!
Currently, we have Delirium as a inferior Inner Release, and this will not change in EW. On the contrary, for what we have seen in the job trailer, Delirium and IR are going to operate even MORE similar than before! SE confirmed that both will give 3 stacks of free beast and blood gauge weaponskills. At least today, IR negates the cost for Onslaught and Upheaval, yet that's going to be removed anyway. The only difference will be critDH for WAR and a tiny bit of MP for DRK.
Blood Weapon is also an inferior Infuriate with high risk thx to its low duration and sensitivity to high ping, which makes BW for many "offshore" peeps unrealiable. Infuritate is also on the charge system and gets its CD reduced after every beast gauge weaponskill. Blood Weapon's "unique" trait is its (up to) 3k MP you get from it for 1 Edge or Flood vs Infuriate's trait to overwrite Fell Cleave with Inner Chaos (and aoe counterpart).
In ShB, DRKs CDs are also more awkward than WAR, thx to its 60s BW burst + 90s Delirium, while WAR only has 90s Inner Release. Tho, this will soon be a thing of the past, as most CDs are going to be adjusted to 60s.
Blood Gauge in general is also similar - if not identical - to Beast Gauge. And as I said above, Onslaught and Upheaval are going to have their costs removed, so that statement is not far off. GCD gauge generation - while slightly different - is generated in the same matter and in 10 point steps. Compare that to other jobs or roles, there are plenty that generate 5 and/or 10 points for certain actions, but WAR and DRK are both limited to 10/20 pts.
Also soon to be homogenised: Onslaught on charges instead of gauge cost, 3 charges, very similar to Plunge with its soon 20y range. Whether those 3 charges vs 2 charges really make a difference is debateable, but for certain, not unique!
Let's ingore roles actions (and actions such as Shadowwall/Vengeance and Grit/Defiance) for now, and there are still at least 50% of DRK actions that are copy and paste actions from WAR sprinkled with different visuals and theme - and your characteristic of DRK having risky, low reward actions (Blood Weapon, old Darkside, DA Dark Mind etc.).
The "DRK is a WAR clone"-thing is not just a meme, it describes the state DRK is currently in!
