Trying to explain to new players that the pretty big new SHIELD healer heals most effectively by stacking 2-3 regens together and that the other shield requires about 5 button presses to put out 2 heals is definitely a factor in the problem of heal button bloat

All healers functionally have the same HPS potential of WHM (or slightly higher) but WHM doesnt beat around the bush by putting it on 15 buttons instead of 3
