Do people not know that the SCH healing pet increases all party members healing by 20% (including the WHM that may be in your 8 man), increases magic resistance by 20% and has a Regen all ability?
Do people not know that the SCH support pet increases spell speed and skill speed by 30% and has a silence ability?
Do people not know that SCHs have both heals, absorb shields, damage reduction shields and cleanses?
How anyone can think a WHM is a better healing class blows my mind. A competent SCH that utilizes all of their abilities can be the difference between a successful run and a wipe, just like a good WHM can.
Also, I would take my FCs WAR over any GLD you can throw at me.
It is all about the player. A great player can make any class seem overpowered compared to a mediocre player.
1. Learn to play your class properly.
2. Play all classes, for comparison.
3. Come back here and if you still feel a class is OP, people might take you seriously.
