A level ten player facing a level twelve player starts the match at a massive mathematical disadvantage before a single card is even played.
Therefore, understanding exactly how to efficiently generate account experience points (XP) is vital for long-term survival on the ladder.

Furthermore, higher level towers deal more damage per shot, altering crucial interactions against enemy swarms.
