Specialists – Each one has it own associated weapon class, pick outrider get assaults rifles with selection of perks suited for that class.  Assault rifles versatile weapons get versatile perks designed to help survivable. Perks like engineer, awarness dead silence could be removed as cost for using versatile weapon class. Mr versatile specialist is given versatile abilities designed to help keep him alive. 

Shotguns for example may have limited range but could be given super powerful perks to help with the class.  Snipers could be impossible to use at close range but given long range style perks with no counter. Bunch of interesting design choices which could be made some examples.

• No perks unlike you get kills with your guns earn perks as you go allowed as many attachments as you want.
• Knife only specialists which moves faster than normal due to perks and has different movement system.
• Pistol only specialist
• Dual wield only specialist
• No perks specialists but has the best weapons in the game

Abilities and weapons – Biggest problem with the specialists most of the abilities and weapons are designed to kill nothing else.  Only couple which can be used in defensive way.  Plus most are based on timing over anything else given how fast you die not that useful.  Would like to see more useful less timed focused abilities and weapons.   Right most of them are not worth using apart from couple which are super powerful.
