The spellslinger, Warrior, Esper and Stalker, make typical core classes of an MMORPG, but in contrast to others there's still lacking a bit, and as we know, there's 2 more classes coming! These two classes will either have high or very little impact on the already existing game balance. Which brings me to speculate if there will not be 6, but an actual 8 classes to choose from, which will all bring something to the table, and actually make 40 man raids a little more interesting, in terms of class diversity. What brings me to speculate this is the following. First of, we have an idea of a rifle/gunner class coming due to the screen shot from pax and the fact none of the listed classes have any listed "Plasma rifle" or anything fancy listed as their dedicated choice of arms. Secondly, in the cinematic trailer the Granok warrior deployed a sentry like turret which may hint at the possibility of an engineer class that can deploy defensive (or depending on how it's used) turrets. Third, Granok so far is the race with the least possible class options so far, if we take into account that a granok deployed a turret in the cinematic trailer that would mean the "engineer" is very possible to be their actual 2nd class, and they should at least have 3 classes open to them, this is more opinion based from my end, which if the 2nd possible new classes would be "stealthy" wouldn't make any sense for a Granok as that's sort of having your Tauren from WoW being a rogue. Fourth, So far Espers and Spellslingers are the current only classes with a healing option (This also goes for Warriors and Stalkers who are the current only tanking options), which strengthens my own opinion based logic, that there should at least be a 3rd, if not 4th option available in the future, in any case a 3rd healing option would generally mean that the so "unannounced stealth class" that we not know of, if it's even an actual class and not a stalker, exists, or doesn't, in this case it would mean next is the gunner + something 3rd the community might not know of as of yet. Fifth, The loot. We all know the jolly old, Heavy Medium and "Panties", armor system. So far it would be safe to assume that Espers would be using cloth, and Warriors Heavy. As in other games with multiple classes it's probably safe to say that there'll be at least 2 classes per armor type, 2 heavy, 2 medium, and 2 cloth to be able to distribute loot between the classes, it's very likely for Stalkers and Spellslingers to be medium which would mean one of the new classes might be a heavy and speculation on the last. Sixth, on the official Wildstar website there's 8 windows on the side, 4 occupy the current known classes, and 2 to be announced, the last 2 might just be there because that was how the site was build due to the fact there's 8 races and decided to "blank" the last 2 in the classes section, or, there's an actual 2 more classes in store!
