Post pointless PvE abilities and how you'd make them relevant.

I could definitely see Thunder 2 having an AoE effect, but it'd force the individual thunder spells to have their own DoT application, similar to 'Miasma/Bio' and 'Miasma II/Bio II'. Perhaps having each spell overwrite each other would prevent issues, in theory. (Casting Thunder 2 while a Thunder spell is ticking, overwrites the Thunder DoT and applies a Thunder 2 DoT) I can also see it becoming pretty powerful, though Flare would probably overwrite its power anyways. Maybe limiting the amount of targets it could hit down to like, 3 enemies.

What I'd like to see from thunder spells, if I'm allowed it dream lol, is:

Thunder 1: Grants a 5% chance after each damage over time tick to cause the next Thunder, Thunder II, or Thunder III to add its full damage over time amount to its initial damage, have no cast time and cost no MP (Literal Thundercloud definition)
Thunder 2: Grants a 10% chance after each damage over time tick to burst, spreading Thunder damage over time to up to 3 nearby targets.
Thunder 3: (insert thundercloud definition). Combo: Thundercloud. Combo Effect: grants a 20% chance on successful hit to grant the user a Fulmination stack.

Burst: Deals Lightning damage with a potency of 300-500(throwing out numbers) to a target and enemies near it. Only available when under the effect of Fulmination. Additional Effect: Lightning Damage over Time. Potency: 35. Duration: 24 seconds.

That would give each thunder spell its own identity, allowing BLMs to have a little more spice into into different scenarios and keeps the randomness of the BLM class large enough to keep it from being OP.
