I logged in just for this. Anyone who played crusader knows how weak the class is. Sunlight isn't just for the debuff removal, support and int builds relied on the cast time removal. Crusader heal has such a long cast time that the boss can get 2+ attacks in before it triggers.
Also, the nuke skill also has like 4 seconds of cast time? Havent played in a while but I remember the cd of it matched sunlight perfectly so you would always be able to cast it when it is up without your party thinking that you went afk.
