Tell us something we don't know already, am I right? 4.2 has clear winners and losers, and with the changes to MNK (a lack thereof for SAM) a lot of people are turning in the blade for a pair of boxing gloves. In fairness, they finally get their expansion that they were promised, but their fellow striker remains an undesired job.
The devs seem very scared to give SAM the power that it needs to be more competitive. Call me crazy, but I think it could use a bit of a boost! We could simply boost its raw DPS, give it a different form of utility.. Maybe make it the sole provider of the slashing debuff like DRG is the sole provider of the piercing debuff? Heck, giving SAM the piercing debuff would be good as well..
I guess they don't see a need to change the job because people play it due to being an easy to access DPS that pulls "big numbers" on its own? The casters are also no longer in such a good spot.. but even they have it marginally better(even if they're overshadowed by MNK).
