I started the game last year in spring and everybody in the low level dungeons saved the limit break for the last boss and 5 - 10% left on his HP. I started as a conjurer and I was like "well, I don't care". But I recognized soon that this behaviour is such a waste of time and damage outputs.

I started the game with an alternate character. In Toto-Rak I have used a Level 1 Limit Break on the tail and the tank said "Oh God why?". Well, the tail was removed instantly and the tank had nothing else to say then "lol".

During my first Ravana fight, nobody used the limit break Level 3. We had it up at 60% of his Health. Why should you wait if you can guarantee that another Limit break 3 will come up during a fight / dungeon? This makes no sense.
