The burst vs. sustained dps debate is not an easy one to solve, but it would be present even if you took raid buffs out of the equation, because having greater burst generally benefits from downtime. But if you give the advantage to sustained dps, it pulls ahead on full uptime fights. But it still comes down to what dps numbers jobs are achieving compared to others within the same raid slot, on the current tier. Removing raid buffs or messing with their timings doesn't change any of that.
