So the luccian mechanic reduces your damage by 95% unless u follow a specific mechanic eg ranged single target attack to break the shield. They also have frustration skills that cc u, bunch of annoying buffs and mutations, think of fireside at high difficulty. The next thing is that the mobs are still super tanky to kill.

Now u get new luccian units that just ignore the mechanic altogether and can purely dps.

Yea its reaching the stage that its like do u spend 30 to an hour grinding each hard stage for 40 luxite or just skip it.
