i don't know if any of this was mentioned before but something i'd like to see in riftrunner would be a better application of the thief/assassin character... a good assassin should be as effective a killer as a good fighter/warrior, but instead of relying on using the most powerful weapon availible an assassin would use luck and ability to his advantage (hamstring special (basically the backstab in divdiv...), sneaking up on an opponent and actually backstabbing by backstabbing (which would cause instant death to weaker, low defense/resistance enemies or a standard 3x damage to tougher opponents), speed killing by doing critical strikes...) with a great focus on skills and a reduced focus on using the best weapon (perhaps even negative bonuses to using heavy shields or nonassassin weapons like broadswords/doubleaxes)...
applied correctly such an idea would add an extra layer of strategy and playability to the game...
