Firstly, thank <insert deity here> for 8 second Transpose. Also, and maybe it's just me, but BLM actually feels playable now (as opposed to in 4.0), so, yay!
As for future changes:
- Sleep, delete or move to cross role. Replace with Focus: +30% direct hit chance, and +10% direct hit damage bonus for 20s, 90s cooldown.
Reason: Since losing Raging Strikes BLM has been seriously lacking a 'burst' buff; being direct hit makes it a bit more interesting than just straight damage.
- Freeze, add additional effect: Grants Umbral Ice III and removes Astral Fire
Reason: Freeze is next to useless, this would allow it to be used instead of Blizzard III for the AoE rotation.
- Scathe, replace with Double Cast: The next two spells will require no cast time. Becomes Triple Cast at Lv66.
Reason: Scathe is mostly useless anyway and Swiftcast was moved to cross-role; introducing a low level instant cast ability would make BLM flow better in pre lv66 content.
- Aetherial Manipulation, change so that if the BLM doesn't have a friendly target it moves the BLM forward 15y. Increase cooldown to 20s.
Reason: Any ability that requires you to switch targets in FFXIV is clunky to use... Removing the target requirement keeps the existing functionality while allowing AM to be used far more easily and in more situations.
- Enochian, lower cooldown to 15s.
Reason: Enochian is little more than an annoying formality at this point, and a 30s cooldown is little more than a punishment for players still learning the job.
- Blizzard IV, increase potency to 280.
Reasons.
- Lay Lines, lower cooldown to 60s. Lower duration to 24s. Now becomes Between the Lines when cast, reverts to Lay Lines when the Lay Lines effect expires.
Reason: QoL, slighty better mobility and overall damage.
- Thundercloud, changed to a stacking proc, max 3 stacks. Next Thunder spell will add 1/3 of it's full damage over time amount per stack to its initial damage, have no cast time, and cost no MP. Chance to proc increased to 25% for Thunder I / III and 8% for Thunder II / IV.
Reason: While the proc duration increase is nice in limited situations, Thundercloud procs are still very hit and miss, this is an attempt to smooth things out a bit by making procs more likely (for the instant cast, no MP) without increasing overall damage output.
- Sharpcast, when used with a Thunder spell it gives a full 3 stacks of Thundercloud.
Reason: Changes to Thundercloud.
- Empower Lay Lines (new ability); triples the radius of the next Lay Lines cast and allows it to affect any party member standing with-in the circle. 180s cooldown.
Reason: Caster meta?
NB. I know a number of these changes would increase BLM overall damage output, but they are 'pure' DPS after all, and potencies are easily adjusted if needed.
