RChu1982: Advocating for a slow Priest or Bishop assumes that you will have an enemy that will cast cloud spells at your party; Thankfully, these are few and far between. I believe that there is only one battle where that is guaranteed, at AP, with Djinni of the Clouds at the Chaos Temple. In that one battle, you could just do what I do, and wipe them out in round 1 with fast magic/ranged attacks.
But can you do that at the levels the game is expecting? (I'm thinking around level 24 for endgame, but many experienced players get there a few levels earlier simply because they know where everything is and end up not fighting as many battles as a result.) Your magic won't be as effective when you're not at the high levels you seem to like.
Also:
* Heal All allows you to heal characters who haven't taken damage as of the start of the round.
* If you cast Resurrect too early in the round, there's a higher chance that the revived character won't survive to the start of the next round.
* There's the opportunity cost of raising Speed/Senses, in that you can't raise other stats instead. If you ignore initiative, these stats are of limited use (though high Speed does help you get extra attacks/swings, at least, though that won't help spellcasting).
* Having average speed really isn't ideal for healers. You can't consistently act first, but you can't consistently act last, either. This means that you could end up eating two full rounds of attacks without having a chance to heal.
* If you kill the enemies too fast, other characters won't get a chance to act, and hence won't get skill experience this round.
* In Continuous mode, being fact isn't as much of an advantage when it comes to healing. In fact, you can have a character defend, and if someone needs a heal later in the round, you can switch the character's action mid-round. (You can't do this in Phased.)
RChu1982: Edit: Note that in my last MDP, the Bard and Gadgeteer had *Light Swords* and *Light Shields*, making them powerful, though not as powerful as a Fighter or Rogue (it's about as powerful as said classes can get in melee). The Battle-Priest or Battle-Bishop would probably be best wielding the Staff of Doom, as they can hit from extended range, and don't have to worry about being hit back most of the time.
Or you could go in the front row with the Diamond Eyes (only one guaranteed, but this means you don't need to give the character the only guaranteed Staff of Doom, and can give it to someone else) or The Mauler (can buy multiple from Ferro). (In my experience from last playthrough (abandoned early because I was getting bored), a human battle bishop is a bit frail in the front ranks; she had a few deaths. On the other hand, a dwarven battle bishop should be more durable, but the one I used was not a front liner, so I sort of want to try one in the front.)
There's also, of course, the strategy of not using close range weapons and only using extended range. This would put, in the front ranks, the following sorts of characters:
* Polearm users. Fighter and Valkyrie are particularly good choices here, with Fighters being more powerful due to the overpowered Berserk ability.
* Giant Sword users (must be Mooks). Fighter, Samurai, and Ranger are good choices here. Again, Fighter is the most powerful.
* One Staff of Doom user. Any class could work, though Bishop may want to choose a durable race such as Dwarf, and I wouldn't recommend Psionic or Mage for this. Again, Fighter works best (and you even get a KO, in addition to the other effects it has), but you can use other classes here. The one class I wouldn't recommend for this is Rogue, because I believe you can't backstab with it, and backstabbing is really the only reason to use a Rogue over another class.
Also, the Light Sword/Shield are rare, and the shield looks so powerful that I consider it to be overpowered and won't use it.
(Also, note that the MDP I'm thinking of, that only uses full casters and no stamina casters, has nobody to use that sword.)
