Influences will still play a role in the game, but the ability to gain them has been diminished. This means that they need to really make sense for your character and the plan to get it needs to be solid. In effect this translates to levels 1 and 2 as realistically attainable, with 3+ becoming very, very, difficult to get. Combining will still be possible, though this does expose a little of your ability to the other person. This also doesn’t mean you can just spread broadly and take 5 influences at level 2… they need to make sense for the character.
