Is it worth having multiple characters and specializing in a particular class? Or will they all end up with all the special abilities anyway?
Whats the point of choosing a side when you create a new one?
You only get 20 skill points - that's enough to get all of the universal skills and all of the skills for a single class, or to get a few key skills for 2 or more classes so that you become a more versatile character.
Personally, I've got three characters set up:
Heavy Character, specializes in soldier and medic
Medium Character, specializes in engineer and soldier
Light character, specializes in medic and operative
If you go into more than one class with a character, you cant get all of the skills for that class, but I find that (engineer aside) most classes have a few skills that really arent all that useful, and arent necessary to play the character well. So far, engineer is the only class that I've taken every single skill on - for the others, there are plenty you can skip to save points (like skipping the adrenaline/metabolism stuff on medic, or sticky grenade/turret control on operative, or some of the grenade skills on soldier). Still, I like to set up each character so that he can effectively play two classes, so that I can always switch if one or the other is needed more in a match.
