Help! I'm having problem healing GNB mass pull.

[MerlinCross]

When I first read the tooltip, I also thought it was only movement speed and only later discovered that it's called "Heavy" and not "Slow".
Same with tooltips about increasing healing magic vs healing actions. I didn't know the difference until I got into raiding. I just thought it increases all healing, I didn't know that the default is that oGCDs are not affected unless stated otherwise.
Some tooltips could do with an update.

Okay but WHY does it work like that with Healing? I didn’t know that either that’s just being obtuse now.

Sorry to take over the topic that’s just weird with tool tips

Healing magic means only GCD heals are affected as they are called "Spells".
Healing actions means everything, both Spells and Abilities, are affected and not limited to magic = Spells.
With some mental gymnastics one could probably get the drift that magic only affects spells while actions means everything but I definitely didn't get it. I never found this to be particulary intuitive and I never understood why they didn't simply write "Increases healing from healing Spells" and "Increases healing from healing Spells and Abilities" instead of magic/ actions. Add "Weaponskills" to include the tank combos if necessary, but we have clear names for each type of skill (Spell, Weaponskill, Ability), why not use them?

As to why... it's probably a relic from ARR/ HW era when we had only very few oGCDs and GCD heals were more bread & butter. So it made sense back then that buffs primarily affected GCD heals as they were the ones you fell back on when lots of healing was required.
