A less unfair approach to giving another advantage to people who already have one could be a change to reinforcements during battles, either through a minor adjustment of the spawn timer or a reduced amount of spawn flags for the smaller side. The side who has more people to reinforce with (ticket-wise, in-game) would have more troops ready to move into battle and the smaller side wouldn't be able to keep the same pace of reinforcement, since they'll run out sooner anyway.
I don't think that giving automatic benefits to one side on a gameplay level for simply having more tickets would be taking the game in a good direction, however, especially considering how easy it is to recruit troops. Taking it a step further, why would we then even need battles at a certain number disparity? Say one side is outnumbered 10 to 1 in tickets, why should there even be a fight? Shouldn't they just lose automatically? No, because it's not fun.
