I have checked some addons I have previously used in vanilla wow and maybe somebody could out by pointing out classic version or adapting it for classic.
Also cannot remember/find the names for this kind of addons:
* Showing mana while in druid forms
* DoTimer alternative?
* Threat counter which would show the number on abilities? How much threat will be generated (it could look similar to theorycraft addon on spells)
* Minimap with icons which appeared in BC/WotLK (class trainer, profession trainer, mail, innkeeper etc.)
P.S. I play on EU-Skullflame. There are 2 Stonespine servers listed here, no skullflame :( GMs plz fix :(
Energy Watch / Druidbar for the mana bar in druid form.
I just use weak auras to manage dots if you just want something simple.
Raikan - Night Elf Druid
Keatts- Human Rogue
Grobbulus - US
Have you checked out https://willitclassic.com/ yet? Might help with your list of addons to see if any have been adapted or already exist.
