With numerous theories floating around about what the 12th class will be, I decided to show you guys some of the patterns I've noticed that has convinced me what type of class we're getting either this expansion or the one afterwards.
Pattern One: Mail Armor
The game lacks a third mail armor wearer. Since every other armor is used by 3 classes.
Pattern Two: Bows, Xbows, Guns
Only one class can use three types of weapons exclusively. That is highly irregular.
Pattern Three: Class balance
The game is divided between pure, semi-hybrid, and hybrid. Pures are entirely DPS.
Semi-hybrids have 2 similar specs, and one different spec. True hybrids can do all roles.
We have 4 pure classes, 4 semi-hybrids, and 3 true hybrids.
There's more patterns beyond the ones showcased here. These are the three big ones. From them my guess would be that the next class is a mail wearer that also uses ranged weapons. Also the class is more likely to be a tri-spec hybrid (tank/dps/heals) like Paladins and Monks.
More to come.
