Well, kinda. They also lose, because "differently" is "they keep the same powers from first level (plus one extra) and just spam low level encounter powers at high level, because that's more effective than playing as designed".

The Essentials BA builds were much more workable as classes that actually played differently (even when they added in a daily-like option like the Assassin Executioner).

OTOH, this is mostly an execution problem (costing high level powers too high relatively to very powerful scaling lower level powers), and likely could have been handled with power level eratta.
