Bump Fire/Blizz IV to 300(Overall 540) potency as we have no OGCDs to keep our damage up like SAM as well as Fire/Blizz IV being above the GCD. If not a potency buff to Fire/Blizz IV, get rid of the above the gcd cast of Fire/Blizz 4, no real reason to keep it anymore. Fire 1 brought up from 180 to 200, Fire III from 240 to 260.
Bump Enochian's Damage up from 5% to 10%.
Then Thunder III's dot potency from 40 to 55. Proc chance for Thundercloud from 10% to 15% and get rid of the duration of the thundercloud buff so we can plan to use.
UI/AF brought up by 2 seconds just like PVP UI/AF.
Triplecast/Leylines recast from 90 to 60.

As of right now, BLM needs to be brought up drastically in damage to make up for the fact that our DPS dies as mechanics happen, but a good BLM that reduces downtime as much as possible should be hitting SAM numbers. Now not all of these should be put in, but just throwing out what would help out BLM and what i think needs to be changed.
