HoT Add-on
 

I'll tryed many ... but no one matched to 100%

1st: Class Timer
-> no multi targer function

2st: Ellipsis
-> HoTs fade for 0,2sec over and over (wrong adjustment?)

3st: NECB
-> too much

any an add-on fitting 4 my play style? im resto dudu but i'll play a shadow priest as well (any add on support both?)
or does anybody knows how to fix ellipsis?

Have you tried HoTCandy yet? That's the one I'm using. It works very well for a resto druid, I think. I don't know how well it works for a priest.

Ellipsis is basically DoTimer recoded. I wasn't aware that the author was still working on Ellipsis.

I'd suggest giving DoTimer a look:

DoTimer's author hasn't been around for a couple of months, so until he returns I'm maintaining a version of his addon with various fixes that have become necessary as some changes have been made to the game since his last update:

ForteXorcist will do all you want and more, if it has too much you can just disable the parts you don't want to use.

This is also what I was going to suggest. As I play all classes, I have all modules enabled. It's an outstanding mod and the spell timers section (I believe) will work wonders for you (make sure to add the priest/druid modules (or whatever class you play)).
