Make all classes worth having by itself. Before everyone jumps in and says all classes count all you have to do is look at the typical group make-ups
2-3 Monks
3-4 W/?? (usually W/Mo)
1-2 E/?? (depending on how many Monks and Warriors)
0-1 "support" class Ranger, Necro, Mesmer (only if their isnt a secondary skill in the group already).
People can say they matter all they want but most groups dont use these types of classes (at least them as primarys) and most are almost dead against them being added to the party or just leave outright. Im not asking for an "Uber leet" classes just these "sopport" classes given a little boost so that they can stand on their own in HoH (personally I just want to see a little variaty in group make-ups). I personally run a R/Me (IMO the funnest classes to use, but after waiting around for 30-40 minutes for a group and another 5 listening to everyone complain to the leader about inviting a Ranger into the group the fun is to few and far between). I shouldnt have to play a monk, warrior or Elementalist to enjoy the game or be an equel part.
