Greetings. I have some ideas
1) To make a function of signal when periodical damage grants a bonus. For example Black Mage's Thunder have a bonus and when this bonus appears the skill on skill bar begin to light. It is not easy always notice when bonus comes, so sound announcing would be nice
2) To make a function of placing marks on the ground. It is very nice to use such marks in raid dungeons- Coil, Crystal Tower
Thank you
