I agree with none of the points in the OP.

1) Optimize your character, conserve MP during fights, use ether, etc.

2) The point is that your CON doesn't start at max rank. You gain these raises as you rank up and each one is an improvement. I would have thought that would be obvious.

3) They're already working on this so it doesn't need mentioning.

4) We need something to spend our gil on. Gil before 1.18 had very few uses and there was massive inflation. Repairs need to cost. We also need a real consequence of death. The current system reduces inflation, increases the appeal of DoH to players, gives death some meaning, and increases the need for party play by making Raise more appealing.

5) Plenty of people can already complete the R45 dungeon. My LS must have completed it a dozen times by now. go to bluegarter.guildwork.com if you want to see videos. The dungeon requires some organization and strategy. The learning curve on it is perfect. It doesn't need a nerf.

6) Relating to point number 5, our gladiators don't seem to have any trouble keeping aggro.
