Some of the newer savage/extreme raids have mechanics that require a melee dps to miss out on positional potencies and true north has too slow of a cool down to cover all of those instances.

If they are set on keeping positionals, I would like the true north CD reduced to 15s to make it fair for the melee's in content like this. More often than not, my team mates will opt to run as ranged dps on these fights so positional mechanics can be ignored, we just bring NIN along for the TA buff.
