Well it does mean enemies can use it in every fight
Still need to test it myself. Use it once in tutorial, but changed weapons afterward.
Not so horrible:
1) one per fight
2) not that many enemies should have it, as it's weapon specific
3) Question: do you need a direct line of sight to charge (like in Gears Tactics)? If so spellcasters still could be protected with right positioning.
Still, a sheer mobility of the skill (wasn't it bonus action as well?) is insane. Quite shocking as well, as other weapon skills that I have used so far have been rather tame in comparioson.
EDIT: Just swapped weapons, and tried it again during the comat encounter before Druid's Grove. I am not clear on how it works. UI wise it looks exactly like RUSH from D:OS2. On the furthers goblin it said "target obscured" which could indicate that direct line of sight was needed. However, I was able to attack goblin which was potentially blocking him, though to get to him I was able to "teleport" through worg. Whenever that was worg not registering properly, or something else was going on, I am not sure.
