Cure kits rightfully died a horrible death as the level when up (and their CE multiplier went down).
Please people, for the love of FFXI learn the actual mechanics behind the enmity system. People have already taken tons of their personal time and done all the hard work, you only need to read.

"Heal spam" has never been better then smacking sh1t to generated hate, notably CE. The only time it was ever useful was when the PLD was unbuffed or not engaged. If SE wants to create "real" tanking then their going to have to attack the core of the problem, there are no significant hate generating abilities in the game on a short enough timer to matter. Alter provoke (just example) to generate 500~1000 CE and then it will be a viable hate tool.
