After the DRK test numbers by a DD, I decided to not test the remaining jobs that can be considered "support" BRD SMN or ?
I am interested in what WHM's think of these numbers. I do not think its being an overpowered job, but by these numbers the gap is clearly widening. For any class other to come even close to matching these numbers, they must sub whm and use the 10minute whm job ability Divine Seal. Additionally, these spells are single target, whereas the new CuragaV and existing CuragaIV are clearly not.
WHM is great as the superpowered healer, however I wouldn't mind getting back to what used to be known as "support healing" For players that just like to change the flavor of their job on occasion, or people who just plain dont want to play on whm, this used to be an option. As higher level tanks/DD start to break the 2k HP mark, these smaller high enmity cures will just not be a viable option.
Also the fact that clearly any job can sub whm and pull off a decent CureIV, nearly equal to what a RDM and most likey SMN and BRD can do. SCH is able to get some higher numbers, but at the cost of using 2-3 seconds of delay to stack job abilities. Note also that at lvl99 all jobs using a subjob of Rdm48 or better will gain access to CureIV.
The last thing I want to see is an obsolete WHM, but when im curing multiple party/alliance members of various status effects while using haste/buffs and curing, I wouldn't mind having someone around with a decent cure to toss out on occasion to back me up.
