MCH and Self-Healing

[Sleigh]

It is strange that they failed to give MCH any form of survivability. It's something like this:

Survivable AF tier:

DRG gets Second Wind, Keen Flurry, mega HP, high DEF and normal MDEF, and even takes less during B4B than others. Can CC Foresight if needed/desired. Arguably multiple mobility options that may save you from being in an AoE (rare but has happened I guess).
BLM gets Manaward, Manawall, and Aetherial Manipulation. Arguably the tankiest DPS, it's DRG or BLM. High MDEF, low DEF, which is better for raids than medium or high DEF and medium MDEF.

Probably not gonna die unless healers are behind or you dun goofed, tier:

MNK gets enhanced Second Wind, Fist of Earth if needed, and can CC Keen Flurry (we had some of our physical DPS CC it for T12 and T13 because why not) and Foresight if needed/desired. Regular DEF and MDEF. Shoulder Tackle, see above.
NIN gets Shade Shift, Second Wind, and Shukuchi. Can CC Keen Flurry if needed/desired. The weakest against magic of the 3 melee, to be sure, but technically the second strongest against stuff like Prey or T13 Earthshakers.
BRD gets Second Wind, and can CC Keen Flurry if needed/desired. Regular DEF and MDEF.

Dang, hope heals are topping you off for mechanics when undergeared, tier:

SMN gets Physick (I guess? You'd never use it while a boss is attackable unless it's do or die) but at least it gets high MDEF.

First to die to Pepsiman Savage tier:

MCH gets ... well, nothing besides Keen Flurry if they want. So far in A1-4S that means A1S Prey and if you so choose to let DPS tank certain enemies in A2S. In fact they have normal MDEF so even though SMN and MCH both get roughly no tools for survival, they get hit harder by raid mechanics.

I'm actually not sure why some DPS get more or less survivability than others; BLM is a given, that's part of their tool set for attacking. DRG being the last to die otherwise over anyone else is strange, MCH getting absolutely nothing is strange, and half the cast being able to really super mitigate physical damage mechanics, rare as they are, while others have nothing, is a bit strange.
