Pros/Cons of each Marauder build

Drain is useless if you plan on making it to 4th job (Which the majority of current Infighters/Marauders do). It's a single target skill, which automatically falls behind Energy Blast, which regardless of it's small delay, is a very powerful mobbing skill that Marauders MUST HAVE to get to 4th job. (This assumes you're not leeching from levels 65~150).

Once you have a decent level of Barrage, you're never going to touch Drain again. This isn't just speaking to Rusty; it's speaking to all Marauders who are actually taking a Drain build into consideration.
