First I would say THM is my Second favorite class in the game and I would like to see some adjustments to its combo's. Also i feel like they should let us recover mp in active mode under a few conditions and also bring back Spirit/Phantom Dart.
THM(BLM) Problems:
1)The problem with THM(BLM) at the moment is that it is forced into using 5 spells for single target damage and only 3 of them being combo spells.
2) One day its gonna get to the point where this class is gonna be singled out and that's not a good thing for people who only want to play one class.
3) Right now THM(BLM) needs more ways to use its spells than just spamming thunder combos(Flash backs of FFXI @.@)
New combos for THM(BLM):
Allow THM(BLM) to be able to convert fire spells into single target, an example of this would be:
Blizzard > Fira > Firaga:
Doing this would ensure that BLM has a way to dmg every monster type in the game with out worry of it fully resisting their spells. As of right now i can't think of any element that resist both Blizzard and Thunder at the same time(could be astral or umbral).

MP Regeneration in active mode:
I Feel every time they make a cool looking weapon for THM/CNJ I think to my self what's the point.
How MP Regeneration currently works:
1) MP starts to regen after a few seconds of standing still.
2) MP can Regen while in combat but only if the monster does not land a hit on you and you are in passive mode. This means the monster would have to miss you about 3 times before your mp started to regen even if you have flashing red hate.
3) Taking any action or moving will reset your mp regen timer to 0, and you will have to wait a few secs again for it to build up.
So that's basically how MP Regen works in passive mode.
If Regen worked the same for active mode as i stated above I feel like we could use the cool weapons they make for us instead of them just being sticks with stat enhancements.
Spirit Dart/ Phantom Dart:
I would love to see these two skills return to THM/CNJ in forms of Ranged AA with some actual animation this time. I also feel the AA dmg should be really weak like it currently is.
