Sylvana, Thank you very much for your suggestions. We already have the "ultimate attack" feature on our list and will implement it for our future World Bosses. In addition to the 50% faster refill timers, we have decided, as you may have already noticed, to keep the limit between any consecutive heals at 30 seconds (usually it may go up to 120 sec after a couple of consecutive heals). This will allow faster heals during this event and will help in defeating the boss faster. We have also added, as suggested in the previous World Bosses, the option to see all the scores - you just have to scroll down in the "Scores" box and click "See all scores".

We hope you are all enjoying this event,

Happy Thanksgiving!
