You have no idea what gimmick means. If you want to see a gimmick fight, try fighting any of the post game bosses in asylum. Specifically, there is a boss that forces you to defend every couple turns or you just lose. Not even because you take damage but because in this specific fight defending increases the time limit.I'm sorry but man... He really laid the artificial difficulty on thick for this DLC. Some enemies that always hit, do % damage, and some cannot be blocked/dodged? Really thought he changed his mind after Onimusha since it pigeonholed you into very specific setups but fuck man.
From a gameplay perspective its really terrible. Imagine if in dark souls they added an area where your vigor, armor and defense doesn't matter one bit and all the enemies can attack you straight through your i-frames and 100% pierce your block.
Really sad the idea of difficulty has taken a hard turn into gimmick fights. I don't need to be told "oh to kill them you just need to do this this and this" I already know, I just feel like it's more pigeonholing.
By the time you get to DLC 3, you play just like any other player. Stack buffs, one shot boss. The domains are there to force you to change up your strategy and the %hp damage prevents bosses from becoming completely trivial regardless of how high your stats get.
Maybe you prefer stat checks you can just grind past though. I'm sure there are plenty of idle games out there for you to watch numbers grow in.
